Internal Combustion Engines (I.C. Engines)

The mechanical efficiency ($${\eta _{\text{m}}}$$) of the engine is given by

A) $${\eta _{\text{m}}} = \frac{{{\text{B}}{\text{.P}}{\text{.}}}}{{{\text{I}}{\text{.P}}{\text{.}}}}$$ B) $${\eta _{\text{m}}} = \frac{{{\text{I}}{\text{.P}}{\text{.}}}}{{{\text{B}}{\text{.P}}{\text{.}}}}$$ C) $${\eta _{\text{m}}} = \frac{{{\text{B}}{\text{.P}}{\text{.}} \times {\text{I}}{\text{.P}}{\text{.}}}}{{100}}$$ D) None of these

Answer & Solution

Correct Answer: Option A

The mechanical efficiency ($${\eta _{\text{m}}}$$) of the engine is given by $${\eta _{\text{m}}} = \frac{{{\text{B}}{\text{.P}}{\text{.}}}}{{{\text{I}}{\text{.P}}{\text{.}}}}$$
