Question

If the efficiency of a camot engine is η, then the coefficient of performance of a heat pump working between the same temperatures will be (A) 1-η (B) (1-η/η) (C) (1/η) (D) 1+(1/η)

Tardigrade Admin · Accepted Answer

Coefficient of performance of heat pump =(1/ text efficiency of Carnot engine )=(1/η)

Q. If the efficiency of a camot engine is $η$ , then the coefficient of performance of a heat pump working between the same temperatures will be

$1 - η$

$\frac{1 - η}{η}$

$\frac{1}{η}$

$1 + \frac{1}{η}$

Coefficient of performance of heat pump $= \frac{1}{efficiency of Carnot engine} = \frac{1}{η}$

Q. If the efficiency of a camot engine is η, then the coefficient of performance of a heat pump working between the same temperatures will be

1−η

η1−η​
