Chapter 15, Problem 34P

To determine

To find : The coefficient of performance.

Answer to Problem 34P

  $0.65$

Explanation of Solution

Given:

Efficiency $=35\%$

Formula Used :

COP + Efficiency of heat pump $=1$

Calculation:

Substituting the values,

  $\Rightarrow \text{COP}+0.35=1$

  $\Rightarrow \text{COP}=1-0.35$

  $\Rightarrow \text{COP}=0.65$
