A heat pump with a performance coefficient (COP)of 4.9 absorbs heat from the atmosphere at a rate of $29 \mathrm {~kW} .$ 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 using the formula: Work = Heat absorbed / COP = 29 kW / 4.9 = 5.918 kW, which is approximately 6 kW.

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