Question 27 POST_UTME_GREENFIELD_UNIVERSITY • 2017 • PHYSICS • objective

A heat engine operates between two temperatures $T_1$ and $T_2$, where $T_1 > T_2$. The engine absorbs $Q_1$ amount of heat from the high-temperature reservoir and rejects $Q_2$ amount of heat to the low-temperature reservoir. Assuming the engine is reversible, find the efficiency $\eta$ in terms of $Q_1$ and $Q_2$.

Answer Options

A. \eta = \frac{Q_1 - Q_2}{Q_1}
Correct Answer B. \eta = 1 - \frac{Q_2}{Q_1}
C. \eta = \frac{Q_2}{Q_1}
D. \eta = \frac{Q_1 + Q_2}{Q_1}
Correct Answer
B
Correct Option:
\eta = 1 - \frac{Q_2}{Q_1}
