A heat pump with a performance coefficient (COP) of 4.9 absorbs heat from the atmosphere at a rate of $29 \mathrm {~kW} \text {. }$ At what rate is work being done to run this heat pump?
A) 6 kW
B) 142 kW
C) 113 kW
D) 35 kW

Question

Quizplus · Accepted Answer

The COP of a heat pump is defined as the ratio of the heat output to the work input. Given COP = 4.9 and heat absorbed = 29 kW, the work done can be calculated as Work = Heat absorbed / COP = 29 kW / 4.9 = 5.92 kW, which is approximately 6 kW.

A Heat Pump with a Performance Coefficient (COP) of 4 29 kW. 29 \mathrm {~kW} \text {. }29 kW.

A Heat Pump with a Performance Coefficient (COP) of 4 $29 \mathrm {~kW} \text {. }$
