207) The high steam and low water safety valve is not used in

Cochran boiler

Cornish boiler

Lancashire boiler

Locomotive boiler

Answer is:

Locomotive boiler

208) In a Woolf type compound engine, the high pressure and low pressure cylinders

have common piston rod

are set at 90 Degree

have separate piston rod

are set in V - arrangement

Answer is:

have separate piston rod

209) The actual power generated in the engine cylinder is called

indicated power

brake power

frictional power

none of these

Answer is:

indicated power

Explanation:

Indicated Power is defined as the power developed by combustion of fuel inside the engine cylinder. It is always more than brake power. Therefore, the difference between IP and BP indicates the power loss in the mechanical components of engine due to friction.

The actual power generated in the engine cylinder is called

210) Which of the following is correct ? (where p_a = Actual mean effective pressure, p_m = Theoretical mean effective pressure, and K = Diagram factor)

p_a = p_m/K

p_a = p_m x K

p_a = K/p_m

p_a = p_m + K

Answer is:

p_a = p_m x K
