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

Question

Quizplus · Accepted Answer

The work done to run the heat pump can be calculated using the formula: Work = Q / COP, where Q is the heat absorbed from the atmosphere (29 kW) and COP is the coefficient of performance (4.9). Thus, Work = 29 kW / 4.9 = 5.918 kW, which rounds to approximately 6 kW.
