Q. The figure shows a heat engine (HE) working between two reservoirs. The amount of heat (Q2) rejected by the heat engine is drawn by a heat pump (HP). The heat pump receives the entire work output (W) of the heat engine. If temperatures, T1 >T3 >T2 , then the relation between the efficiency (h ) of the heat engine and the coefficient of performance (COP) of the heat pump is
| (A) COP=η | (B) COP=1+η | |||
| (C) COP=η-1 | (D) COP=η-1 -1 |
Ans: COP=η-1
Sol:
