Efficiency of a heat engine working on Carnot cycle between two temperature levels depends upon the__________________?
Correct answer: B. Two temperatures only
- A. Pressure of working fluid
- B. Two temperatures only
- C. Mass of the working fluid
- D. Mass and pressure both of the working fluid
Explanation
Carnot efficiency is η = 1 - Tcold/Thot, using absolute temperatures, so it depends only on the two reservoir temperatures. It is independent of the working fluid's mass and pressure.
