Advantage and disadvantages of Bessemer process of steel making
Advantages:
- allowed steel to be produced without fuel
- using the impurities of the iron to create the necessary heat
- reduced the costs of steel production
Disadvantages:
- could convert only a pig iron low in phosphorus and sulfur
- these elements could have been removed by adding a basic flux such as lime, but the basic sl*g produced would have degraded the acidic refractory lining of Bessemer's converter.

Explanation:
Compute the theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5o, respectively. The atomic weight of carbon is 12.01 g/mol.
The theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5° respectively is; 3.54 g/cm³
What is the Theoretical Density?
The first thing we will do is to get the unit cell edge length from the given C - C distance.
From the structure of diamond;
Φ = ¹/₂ * bond angle
Φ = ¹/₂ * 109.5°
Φ = 54.75°
Thus;
θ = 90° - 54.75°
θ = 35.25°
Let the height from a point to the base of the cube of the structure be x. Thus;
x = a/4 = y sin θ
where a is unit cell edge length and y is C -C length. Thus;
a = 4y sin θ
a = 4 * (0.154 * 10⁻⁹) * sin 35.25°
a = 3.56 * 10⁻⁸ cm
The unit cell volume is;
V_c = a³
Thus; V_c = (3.56 * 10⁻⁸)³
V_c = 4.51 * 10⁻²³ cm³
Now, there are 8 equivalent atoms per unit cell and as such density is calculated from;
ρ = (n * A_c)/(V_c * N_a)
A_c is atomic weight of diamond = 12.01 g/mol
N_a is avogadro's number = 6.022 * 10²² atoms/g
Thus;
ρ = (8 * 12.01)/(4.51 * 10⁻²³ * 6.022 * 10²²)
ρ = 3.54 g/cm³

Technician A says that the cylinders should be bored and/or honed to match the size of the pistons to be used. Technician B says that bolt holes should be chamfered and cleaned with a thread chaser before assembly. Who is right
Answer:Both Technician A and Technician B are right.
Explanation: The cracks in an engine can be detected when the engines are thoroughly cleaned because the transmission vent is basically designed to vent hot air.
Also pressure testing can equally detect cracks easily. When you increase the pressure,you will notice leaks from the blocks or cylinder indicating a crack on them.
