How do you determine the efficiency of a heat engine?

Sample interview questions: How do you determine the efficiency of a heat engine?

Sample answer:

1. Define the efficiency of a heat engine: The efficiency of a heat engine is defined as the ratio of the net work done by the engine to the heat absorbed from the high-temperature reservoir.

2. Calculate the net work done by the engine: The net work done by the engine is the difference between the work done by the engine on the surroundings and the work done by the surroundings on the engine.

3. Calculate the heat absorbed from the high-temperature reservoir: The heat absorbed from the high-temperature reservoir is the amount of heat transferred from the high-temperature reservoir to the engine.

4. Substitute the values into the efficiency equation: Read full answer
