In a Carnot engine, if the work done during isothermal expansion is \(25 \%\) more than the work done during isothermal compression, then the efficiency of the engine isz
- A \(10 \%\)
- B \(15 \%\)
- C \(20 \%\)
- D \(25 \%\)
Answer & Solution
Correct Answer
(C) \(20 \%\)
Step-by-step Solution
Detailed explanation
\(W_H = 1.25 W_C\) \(\eta = \frac{W_H - W_C}{W_H}\) \(\eta = \frac{1.25 W_C - W_C}{1.25 W_C}\) \(\eta = \frac{0.25 W_C}{1.25 W_C}\) \(\eta = 0.20 = 20 \% \)
