Steam Boilers and Engines MCQ with Answers

206) The function of a piston in a steam engine is

Answer is:

to convert heat energy of the steam into mechanical work to exhaust steam from the cylinder at proper moment

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

Answer is:

Locomotive boiler

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

Answer is:

have separate piston rod

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

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)

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

pa = pm x K
