IC Engines and Nuclear Power Plants MCQ with Answers

201) The power actually developed by the engine cylinder of an I.C. engine is known as

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.
