A thermodynamic pump with a performance coefficient (COP)of 4.9 absorbs thermal energy from the atmosphere at a rate of $29 \mathrm {~kW} \text {. }$ At what rate is work being done to run this thermodynamic pump?

Question

Quizplus · Accepted Answer

The work done to run the pump is calculated using the formula $W = \frac{Q}{COP}$, where $Q = 29 \mathrm {~kW}$ and $COP = 4.9$. Thus, $W = \frac{29}{4.9} = 5.918 \approx 6 \mathrm {~kW}$.

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