Level 5 taping provides a very smooth surface by? a) One coat of mud and tape 4" knife b) Two coats of mud and tape 4" and 6" knifes c) Three coats of mud with tape 4", 6" and then 8-12" knifes d) Entirely skim coating the wall board to fill all the pores

Answers

Answer 1

The correct option (c). Three coats of mud with tape 4", 6" and then 8-12" knives.

Level 5 taping provides a very smooth surface by three coats of mud with tape 4", 6" and then 8-12" knives.

The Level 5 Taping process involves covering the entire surface of the wallboard with three separate coats of joint compound.

The first coat of joint compound is used to embed the tape and eliminate any bubbles or wrinkles in the tape. For the second coat, the drywall contractor uses a six-inch joint knife to apply a thin layer of joint compound over the tape.

This coat should be allowed to dry completely.

The third and final coat is where the smoothness comes in. This coat involves using an eight to twelve-inch joint knife to apply a thin layer of joint compound over the entire surface of the wallboard.

This coat should be allowed to dry completely. After the third coat is completely dry, the wallboard is sanded smooth, and the dust is removed before the primer and paint are applied.

State the oxidation state of the central metal cation, coordination number and the geometry of the following complexes. (i) Na[Au(CN)_2]

Answers

the oxidation state of the central metal cation (Au) is +3, the coordination number is 2, and the geometry is linear for the complex Na[Au(CN)2].

In the complex Na[Au(CN)2]:

- The oxidation state of the central metal cation, Au, can be determined by considering the charges of the ligands and the overall charge of the complex. Here, the ligands are (CN)2, and each CN ligand has a charge of -1. Since there are two CN ligands, their total charge is -2. The overall charge of the complex, Na[Au(CN)2], is +1 (due to the Na+ cation). Therefore, we can calculate the oxidation state of Au as follows:

  Au + (-2) = +1

  Au = +3

So, the oxidation state of the central metal cation, Au, is +3.

- The coordination number refers to the number of ligands attached to the central metal cation. In this complex, there are two cyanide ligands (CN)2 bonded to the central gold cation (Au), so the coordination number is 2.

- The geometry of the complex can be determined based on the coordination number and the nature of the ligands. In this case, with a coordination number of 2, the geometry is linear.

Therefore, the oxidation state of the central metal cation (Au) is +3, the coordination number is 2, and the geometry is linear for the complex Na[Au(CN)2].

Answers

The volume of the solid formed when the region bounded by the curves y = x³ + 1, x = 1, and y = 0 is rotated about the x-axis is 162 cubic units.

To find the volume, we can use the method of cylindrical shells. The height of each shell is given by the difference between the curves y = x³ + 1 and y = 0, which is y = x³ + 1.

The radius of each shell is the x-coordinate. Integrating the volume of each shell from x = 1 to the x-coordinate of the point where the curves intersect, we can calculate the total volume.

The point of intersection between the curves y = x³ + 1 and y = 0 occurs when x³ + 1 = 0, which implies x = -1. Thus, the integral becomes ∫[1, -1] 2πx(x³ + 1) dx, which evaluates to 162 cubic units after solving the integral.

Elements in one specific (e.g. left) portion are smaller than the selected pivot. O d. The selected pivot is already in the right position in the final sorting order.

Answers

The question asks which statement is wrong after each iteration of quick sorting. The options are:

a) None of the other answers,

b) Elements in one specific portion are larger than the selected pivot,

c) Elements in one specific portion are smaller than the selected pivot, and

d) The selected pivot is already in the right position in the final sorting order. We need to determine which statement is incorrect during the process of quick sorting.

Quick sort is a sorting algorithm that works by partitioning an array based on a selected pivot element and recursively sorting the subarrays. During each iteration of quick sorting, the elements are rearranged to ensure that elements smaller than the pivot are on one side, and elements larger than the pivot are on the other side.

Option a) None of the other answers is not necessarily wrong after each iteration of quick sorting. Depending on the specific elements and pivot chosen, it is possible for none of the other statements to be incorrect.

Option b) Elements in one specific portion being larger than the selected pivot is a correct observation during quick sorting. In the partitioning process, elements larger than the pivot are moved to the right portion of the array.

Option c) Elements in one specific portion being smaller than the selected pivot is also a correct observation during quick sorting. Elements smaller than the pivot are moved to the left portion of the array.

Option d) The selected pivot is already in the right position in the final sorting order is incorrect. In each iteration, the pivot is selected to be in a position such that elements on its left are smaller and elements on its right are larger. The pivot itself may need to be moved during the partitioning process.

Therefore, the correct answer is option d) The selected pivot is already in the right position in the final sorting order, as it is incorrect to assume that the pivot is always in its final sorted position after each iteration of quick sorting.

What is hydraulic conductivity and the result with the
influence of temperature and void ratio? (sand)

Answers

Hydraulic conductivity of sand is influenced by temperature and void ratio, affecting the ability of water to flow through the material.



Hydraulic conductivity is the property of a porous material, such as sand, to transmit water and is influenced by temperature and void ratio.

Hydraulic conductivity refers to the ability of a porous medium, like sand, to allow water to flow through it. It is a crucial parameter in hydrogeology and civil engineering, as it directly affects the movement of groundwater and the efficiency of various geotechnical projects, such as foundation design or landfill containment systems. The hydraulic conductivity of a material is influenced by two primary factors: temperature and void ratio.

Temperature plays a significant role in hydraulic conductivity, as it affects the viscosity of water. As the temperature increases, the water's viscosity decreases, leading to higher hydraulic conductivity. This means that in warmer conditions, water can flow more easily through the sand, allowing for faster movement of groundwater.

The void ratio is another critical factor influencing hydraulic conductivity. Void ratio refers to the ratio of the volume of voids (empty spaces) in the material to the volume of solids. In sandy soils, a higher void ratio indicates a more permeable material, which results in higher hydraulic conductivity. When voids are well-connected, water can pass through more readily, increasing the overall conductivity of the sand.

A 99.6 wt.% Fe-0.40 wt.% C alloy exists at just below the eutectoid temperature. Determine the following for this alloy. (a) Composition of cementite (Fe3C) and ferrite (a) (b) The amount of cementite in grams that forms per 100 g of steel (c) The fraction of pearlite and proeutectoid ferrite (a) (d) Describe microstructure at room temperature.

Answers


Main Answer:
(a) The composition of cementite and ferrite can be determined using the lever rule.
(b) The amount of cementite formed per 100 g of steel can be calculated using the weight percent composition of carbon and the molar mass of cementite.
(c) The fraction of pearlite and proeutectoid ferrite can be determined based on the eutectoid reaction, with pearlite being the predominant microstructure at room temperature.

Explanation:

(a) The composition of cementite (Fe3C) and ferrite (α) in the 99.6 wt.% Fe-0.40 wt.% C alloy just below the eutectoid temperature can be determined using the lever rule. Cementite is a compound of iron and carbon, while ferrite is a solid solution of iron and carbon.

Explanation: The lever rule is a method used to determine the phase fractions in an alloy. In this case, we can use it to find the composition of cementite and ferrite. The lever rule states that the fraction of a phase is equal to the distance between the alloy composition and the phase boundary divided by the distance between the two phase boundaries.

(b) The amount of cementite that forms per 100 g of steel can be calculated using the weight percent composition of carbon and the molar mass of cementite.

Explanation: Since we know the weight percent composition of carbon in the alloy (0.40 wt.%), we can assume that the remaining weight percent (99.6 wt.%) is iron. From this information, we can calculate the molar mass of cementite (Fe3C) and determine the amount of cementite formed per 100 g of steel.

(c) The fraction of pearlite and proeutectoid ferrite (α) can be determined based on the eutectoid reaction.

Explanation: The eutectoid reaction occurs at the eutectoid temperature and results in the formation of pearlite, which is a lamellar structure composed of alternating layers of cementite and ferrite. The proeutectoid ferrite is the ferrite phase that exists before the eutectoid reaction takes place. By understanding the eutectoid reaction and the phase transformations that occur, we can determine the fraction of pearlite and proeutectoid ferrite in the alloy.

(d) At room temperature, the microstructure of the alloy just below the eutectoid temperature will consist of pearlite.

Explanation: When the alloy is cooled to room temperature, the phase transformation from austenite (γ) to pearlite occurs. Pearlite is a lamellar structure composed of alternating layers of cementite and ferrite. Therefore, the microstructure of the alloy at room temperature will consist mainly of pearlite.

8. Let R the relation defined in Z as follows... For every m, n E Z, mRn4|m-n a) Prove the relation is an equivalence relation. F
b) Describe the distinct equivalence classes of R

Answers

The relation R defined on Z as mRn if and only if 4 | (m - n) is an equivalence relation.

a) To prove that the relation R is an equivalence relation, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For every integer n, we need to show that n R n, i.e., n - n is divisible by 4. This is true because n - n equals 0, and 0 is divisible by any integer, including 4. Therefore, R is reflexive.

Symmetry: For every pair of integers m and n, if m R n, then we need to show that n R m. This means that if m - n is divisible by 4, then n - m should also be divisible by 4. This property holds because if m - n is divisible by 4, then -(m - n) = n - m is also divisible by 4. Therefore, R is symmetric.

Transitivity: For every triplet of integers m, n, and p, if m R n and n R p, then we need to show that m R p. This means that if both m - n and n - p are divisible by 4, then m - p should also be divisible by 4. This property holds because if m - n and n - p are divisible by 4, then (m - n) + (n - p) = m - p is also divisible by 4. Therefore, R is transitive.

Since R satisfies all three properties of reflexivity, symmetry, and transitivity, it is an equivalence relation.

b) The distinct equivalence classes of R can be described as follows:

The equivalence class of an integer n contains all integers m such that m R n, i.e., m - n is divisible by 4. In other words, all integers in the same equivalence class have the same remainder when divided by 4.

There are exactly four distinct equivalence classes: [0], [1], [2], and [3].

The equivalence class [0] consists of all integers that are divisible by 4, such as ..., -8, -4, 0, 4, 8, ...

The equivalence class [1] consists of all integers that have a remainder of 1 when divided by 4, such as ..., -7, -3, 1, 5, 9, ...

The equivalence class [2] consists of all integers that have a remainder of 2 when divided by 4, such as ..., -6, -2, 2, 6, 10, ...

The equivalence class [3] consists of all integers that have a remainder of 3 when divided by 4, such as ..., -5, -1, 3, 7, 11, ...

Let's consider the product of two functions, one from the trigonometric category and the other from the rational category, such as:

To find the x-intercept of the function, we set f(x) equal to zero and solve for x:

0 = sin(x) * (1/x)

Since sin(x) cannot equal zero for any x, the only way for the product to be zero is if (1/x) equals zero. However, 1/x is undefined at x = 0, so there is no x-intercept for this function.

To find the y-intercept, we substitute x = 0 into the function:

The liquid phase reactions in a perfectly isolated CSTR are characterized by the following additional data: CpD = 50 cal/mol K, ΔHrxn1 = -3000 cal/mol at 300 K, and ΔHrxn2 = -5000 cal/mol at 300 K.

In a perfectly isolated CSTR, the main answer to the question is that the enthalpy change of reaction (ΔHrxn) can be calculated using the formula:

ΔHrxn = ΔHrxn1 + ΔHrxn2

where ΔHrxn1 is the enthalpy change for reaction 1 and ΔHrxn2 is the enthalpy change for reaction 2.

The supporting explanation is that in a perfectly isolated CSTR, the enthalpy change of reaction can be determined by summing the individual enthalpy changes for each reaction. In this case, ΔHrxn1 is -3000 cal/mol and ΔHrxn2 is -5000 cal/mol. Therefore, the total enthalpy change of reaction is:

ΔHrxn = -3000 cal/mol + (-5000 cal/mol)
      = -8000 cal/mol

It's important to note that the enthalpy change is additive because the reactions are carried out in the same system. The negative sign indicates an exothermic reaction, where heat is released. The value of CpD, which is the heat capacity of the reactants, is not needed for this calculation.

Color blindness is a sex-linked, uncharted condition that is much more common among men than women: Suppose that 6% of all men and 0.6% of all women are color blind. A person is chom (You may assume that 50% of the population are men and 50% are women)
The conditional probability that a person is male is (Type an integer or a fraction).

Answers

The conditional probability that a person is male is 1.

The conditional probability that a person is male can be calculated using the information provided. We are given that 6% of all men are color blind and that 0.6% of all women are color blind. Additionally, we are told that 50% of the population are men and 50% are women.
To calculate the conditional probability, we can use the formula:
Conditional Probability = Probability of an event A given event B has occurred / Probability of event B.
In this case, the event A is being male and the event B is being color blind.
Let's calculate the probability of event B, which is the probability of being color blind. We are told that 6% of all men are color blind and 0.6% of all women are color blind. Since 50% of the population are men and 50% are women, we can calculate the probability of event B as follows:
Probability of event B = (Probability of being male * Probability of being color blind for men) + (Probability of being female * Probability of being color blind for women)
Probability of event B = (0.5 * 0.06) + (0.5 * 0.006) = 0.03 + 0.003 = 0.033
Now, let's calculate the probability of event A given event B, which is the probability of being male given that the person is color blind. We can use the formula:
Conditional Probability = Probability of event A and event B / Probability of event B
Since we are looking for the probability of being male given that the person is color blind, the probability of event A and event B is the same as the probability of event B.
Conditional Probability = Probability of event B / Probability of event B = 0.033 / 0.033 = 1
Therefore, the conditional probability that a person is male is 1.

Given the following information about a typical construction assembly 12" Concrete Block (Sand & gravel - oven-dried) Outside Surface (15 mph) 4" Fiberglass batt insulation Inside surface (Vertical position & horizontal heat flow) 2 layers of 1/2" gypsum board.

We are to determine the approximate U-Factor for the assembly.

Let's first define what U-Factor is before solving the problem.

What is U-Factor?U-factor (or U-value) is the measure of a material's ability to conduct heat. It is expressed as the heat loss rate per hour per square foot per degree Fahrenheit difference in temperature (Btu/hr/ft2/°F).

The lower the U-factor, the greater the insulating capacity of the material.

To solve the problem, we are to first determine the R-Value of the materials.

R-Value is the measure of a material's resistance to conduct heat.

The R-value is equal to the thickness of the material divided by its conductivity.

The sum of the R-values of the materials that make up the assembly will give us the total R-Value.

Then the U-Factor will be the reciprocal of the total R-Value.

To calculate the total R-Value, we need to look up the R-Values of the materials in a reference table.

Using a reference table, we have;The R-Value for 4" Fiberglass batt insulation = 4.0 × 3.14 = 12.56

The R-Value for 2 layers of 1/2" gypsum board = 0.45 × 2 = 0.90

Total R-Value = R-Value of Concrete Block + R-Value of Insulation + R-Value of Gypsum Board

Outside Surface = 0.17

Concrete Block = 1.11

Insulation = 12.56

Gypsum Board = 0.90

Inside surface = 0.68

Total R-Value = 0.17 + 1.11 + 12.56 + 0.90 + 0.68 = 15.42

The U-Factor is the reciprocal of the total R-Value;U-Factor = 1 / R = 1 / 15.42

Answers

Answer: June had 100 buttercups before she gave any out

Step-by-step explanation:

Let's suppose that June had "x" number of buttercups in the beginning.On Monday, June gives 1/4 of the buttercups to Tess, which means she has only 3/4 of the buttercups left. Therefore, the number of buttercups left with her is 3/4 of x, which can be written as 3x/4.On Tuesday, she gives 1/3 of the remaining buttercups to Gail. Therefore, the number of buttercups remaining with June can be represented as (2/3) × (3x/4), which is equal to 2x/4 or x/2.On Wednesday, she gives 3/5 of the remaining buttercups to George. Therefore, the number of buttercups remaining with June can be represented as (2/5) × (x/2), which is equal to x/5.Given that, June has 20 buttercups left, we can represent the above information in the form of an equation.x/5 = 20Multiplying both sides by 5 gives us,x = 100Therefore, June had 100 buttercups in the beginning.

Answers

We can use the ideal gas law and the mass rate formula to calculate the time required for the pressure to be reduced from an initial 1000 kPa to a pressure of 500 kPa. The time t is 32.95 hours.

The law of perfect gases is also known as Ideal Gas Law. It describes the behavior of a gas when all its variables are kept constant. It is given as follows:

pV = nRT

Where p is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

The unit for pressure is Pascals (Pa), volume is cubic meters (m³), number of moles is moles (mol), gas constant is joules per Kelvin per mole (J/mol.K), and temperature is Kelvin (K).

We have constant volume (V) and temperature (T), and we are considering only pressure (p) as the variable. We can use this formula:

dm/dt = -pA√(RT/M)

The rate of mass is (dm/dt), pressure is p, the area of the hole is A, R is the gas constant, T is the temperature, and M is the molar mass of the gas.

The negative sign indicates that the mass rate is flowing out of the tank

We have:

Initial pressure (P1) = 1000 kPa

Final pressure (P2) = 500 kPa

Leakage rate (m) = 0.66pA√(RT/M)

The leakage rate can be written as dm/dt = -0.66pA√(RT/M)

We have a constant volume (V), so we can write:

pV = nRT

The number of moles can be written as:

n = (pV)/(RT)

We can use this formula for the ideal gas law:

pV = nRT

We can substitute this into our mass rate formula to get:

-0.66pA√(RT/M) = -dm/dt(pV/M) (A)(√(RT/M))

Substitute the values of A, p, R, T, M, P1, and P2 to get:

[tex](1000*5*10⁻⁶)/(39.9*516*(273+27)) = ln(1000/500)[/tex]

[tex]t = (5*10⁻⁶)/(0.66*(10⁻⁶)*√(516*5*39.9/0.66))*(ln(1000/500))[/tex]

t = 32.95 hours

We can use the ideal gas law and the mass rate formula to calculate the time required for the pressure to be reduced from an initial 1000 kPa to a pressure of 500 kPa. We can write pV = nRT to get the number of moles as n = (pV)/(RT).

We can substitute this into our mass rate formula to get -

[tex]0.66pA √(RT/M) = -dm/dt(pV/M)(A)(√(RT/M)).[/tex]

Answers

The force in member AB is 12 kN.

To calculate the force in member AB, we need to consider the given values of E, Gas, H, Kas, Las, and Nas. The force in member AB can be determined by analyzing the equilibrium of forces at joint B.

In the given question, E represents the force in member EA, which is 9 kN. Gas represents the force in member GA, which is 5 kN. H represents the force in member HA, which is 3 kN.

To find the force in member AB, we need to consider the forces acting on joint B. From the given information, we know that member AB is connected to members GA and HA. Therefore, the forces in members GA and HA will contribute to the force in member AB.

The force in member GA (5 kN) acts away from joint B, while the force in member HA (3 kN) acts towards joint B. By adding these two forces together, we get a resultant force of 8 kN acting away from joint B.

However, we also need to take into account the external forces acting on joint B. The given values of Kas, Las, and Nas represent the external forces in the x-direction, y-direction, and z-direction respectively. These external forces do not have any impact on the force in member AB.

Hence, the force in member AB is determined solely by the forces in members GA and HA, which give us a total force of 8 kN away from joint B. Therefore, the force in member AB is 8 kN.

Answers

The head acting on the turbine equation is option (2) 87.66 m.

Given,

Sea water (SG=1.03) is flowing at 13160 gpm through a turbine in a hydroelectric plant.

Turbine is to supply 680 hp to another system.

Mechanical efficiency, η = 69 % .

We need to calculate the head acting on the turbine.

The formula for power is

P = Q * g * h * ρ * η

Where,P = power (hp)

Q = flow rate (gpm)

g = acceleration due to gravity (32.2 ft/s²)

h = head (ft)

ρ = density (lb/ft³)

η = efficiency

First, we need to convert gpm to ft³/s.

1 gpm = 0.002228 m³/s

≈ 0.000449 ft³/s

So, flow rate Q = 13160 * 0.000449

= 5.905 ft³/s

Density, ρ = SG * ρwater

= 1.03 * 62.4

= 64.272 lb/ft³

Power, P = 680 hp

Efficiency, η = 69 %

= 0.69

Substitute the values in the above equation as shown below.

P = Q * g * h * ρ * η

680 = 5.905 * 32.2 * h * 64.272 * 0.69

On solving the above equation, we get

h ≈ 87.66 m

Hence, the correct option is (2) 87.66 m.

8. Is the set of functions f(x)=3e" and f(x)=-3e³ independent? Show using the Wronskian. (3pt)

Answers

The set of functions f₁(x) = 3e^x and f₂(x) = -3e^3x is linearly independent since their Wronskian, W(f₁, f₂) = -18e^(4x), is not identically zero.

To determine the independence of the set of functions f₁(x) = 3e^x and f₂(x) = -3e^3x, we can use the Wronskian.

The Wronskian of two functions is given by the determinant of the matrix:

| f₁(x)   f₂(x) |

| f₁'(x)  f₂'(x) |

Let's calculate the Wronskian of f₁(x) = 3e^x and f₂(x) = -3e^3x:

| 3e^x    -3e^3x   |

| 3e^x    -9e^3x   |

Expanding the determinant, we have:

W(f₁, f₂) = (3e^x)(-9e^3x) - (3e^x)(-3e^3x)

         = -27e^(4x) + 9e^(4x)

         = -18e^(4x)

Since the Wronskian is not identically zero (it is equal to -18e^(4x)), we can conclude that the functions f₁(x) = 3e^x and f₂(x) = -3e^3x are linearly independent.

Which graph represents a reflection of f(x) = One-third(9)x across the x-axis?

Answers

Reflection transformation is equivalent to reflecting the function f(x) = (1/3)(9)x across the x-axis.

The correct answer is option D.

When reflecting a function across the x-axis, the y-values of the function are negated while the x-values remain the same. In other words, each point (x, y) on the original function f(x) is transformed to (x, -y) on the reflected function.

In the given question, the function f(x) = (1/3)(9)x represents a linear function with a slope of 9/3 = 3. When we reflect this function across the x-axis, the negative sign is applied to the y-values, resulting in the function f'(x) = -(1/3)(9)x.

Therefore, the correct option that represents the transformation of reflecting the function f(x) = (1/3)(9)x across the x-axis is:

D. Reflection

This option correctly identifies the transformation involved in the reflection process. Reflection is a transformation that flips an object or function across a given axis, in this case, the x-axis. It preserves the shape and orientation of the function while changing the sign of the y-values.

By selecting option D, you would be indicating that the reflected function is obtained by negating the y-values of the original function f(x) = (1/3)(9)x. This transformation is equivalent to reflecting the function across the x-axis.

The maximum lateral pressure behind a vertical soil mass is 100 {kPa} . In order to reinforce the soil mass, steel ties are used with a maximum allowable tensile force of 15 {kN}

Answers

The required area of the soil mass is 0.15 square meters.

The maximum lateral pressure behind a vertical soil mass is 100 kPa. To reinforce the soil mass, steel ties are used with a maximum allowable tensile force of 15 kN.

To calculate the required number of steel ties, we need to determine the force exerted by the soil mass on the ties. This force can be calculated using the lateral pressure and the area of the soil mass. The force exerted by the soil mass on the ties can be calculated using the formula:

Force = Lateral Pressure × Area

Given that the maximum lateral pressure is 100 kPa, we can convert it to N/m² (Pascal) by multiplying by 1000:

100 kPa × 1000 N/m²/kPa = 100,000 N/m²

Now, let's assume the area of the soil mass is A m². Therefore, the force exerted by the soil mass on the ties is:

Force = 100,000 N/m² × A m²

Since the maximum allowable tensile force of the steel ties is 15 kN, we can convert it to N:

15 kN × 1000 N/kN = 15,000 N

Now, we can set up an equation to find the required area of the soil mass:

100,000 N/m² × A m² = 15,000 N

Simplifying the equation, we have:

A m² = 15,000 N / 100,000 N/m²

A m² = 0.15 m²

Therefore, the required area of the soil mass is 0.15 square meters.

Keep in mind that this calculation assumes a uniform lateral pressure behind the soil mass. In practical situations, the lateral pressure may vary, and additional factors should be considered for accurate reinforcement design. It's always advisable to consult a professional engineer for specific project requirements.

A stream of crude oil has a molecular weight of 4.5x10² kg/mol and a mean average boiling point of 370 °C. Estimate the followings: 1. The crude specific gravity at 60 °F? 2. The crude gravity (API°) at 60 °F? 3. Watson characterization factor? 4. Refractive index? 5. Surface tension? 6. Is this crude oil paraffinic, naphthenic or aromatic? Explain, briefly and qualitatively.

Answers

The crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Specific gravity at 60 °F: 0.88

API° at 60 °F: 28

Watson characterization factor: 1.014

Refractive index: 1.44

Surface tension: 20 dyne/cm

Paraffinic, naphthenic, or aromatic: Paraffinic

Specific gravity at 60 °F the specific gravity of a liquid is its density relative to the density of water. The specific gravity of crude oil is typically between 0.8 and 1.0. A specific gravity of 0.88 means that the crude oil is 88% as dense as water.

API° at 60 °F: The API°, or American Petroleum Institute gravity, is a measure of the lightness or darkness of crude oil. A higher API° indicates a lighter crude oil. A crude oil with an API° of 28 is considered to be a medium-heavy crude oil.

Watson characterization factor the Watson characterization factor is a measure of the aromaticity of crude oil. A higher Watson characterization factor indicates a more aromatic crude oil. A crude oil with a Watson characterization factor of 1.014 is considered to be a paraffinic crude oil.

Refractive index the refractive index of a liquid is a measure of how much light is bent when it passes through the liquid. The refractive index of crude oil is typically between 1.4 and 1.5. A refractive index of 1.44 indicates that the crude oil is slightly more refractive than water.

Surface tension the surface tension of a liquid is a measure of the force that acts at the surface of the liquid, tending to minimize the surface area. The surface tension of crude oil is typically between 20 and 30 dyne/cm. A surface tension of 20 dyne/cm indicates that the crude oil has a relatively high surface tension.

Based on the estimated values, the crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Find the coordinates of each point in the resulting image
D'(__) E (__) F'(__) G'(__)
What scale factor did we multiply the coordinates of the original preimage by in order to get the
coordinates of the resulting image?

Answers

1. The coordinates of object

D = (0,0)

E = (5,0)

F = (5,6)

G = (5,0)

2. The coordinates of the image is

D' = (0,0)

E' = ( 15,0)

F' = ( 15, 18)

G' = (15,0)

3. The scale factor is 3

What is coordinate?

Coordinate is any of a set of numbers used in specifying the location of a point on a line, on a surface, or in space.

For example (6,3) is a coordinate and 6 represent the value on x axis and 3 represent the value on y axis.

1. Finding the coordinates ;

The coordinate of the object is

D = (0,0)

E = (5,0)

F = (5,6)

G = (5,0)

2. The coordinates of the image is

D' = (0,0)

E' = ( 15,0)

F' = ( 15, 18)

G' = (15,0)

3. Scale factor = new dimension/original dimension

= 18/6

= 3

In this system, the volatile product is steam, which is condensed and stored. Assuming that the slaked lime powder is 40% of its bulk density, and that the heat evolved by condensing steam is wasted, calculate the heat storage capacity in kWh per cubic metre of Ca(OH)2. DATA: Ca(OH)2(s) CaO(s) + H20(9) AH, = 109 kJ/mol H2O(1) H2O(g) AH, = 44 kJ/mol Bulk density of Ca(OH)2 = 2240 kg/m In which practices do you show care, respect, and integrity to learners colleagues, parents, and other education stakeholders?
