A) 1.86 kW
B) 3.72 kW
C) 7.44 kW
D) 18.60 kW
Correct Answer: D
Solution :
\[{{(COP)}_{th}}=\frac{{{T}_{2}}}{{{T}_{1}}-{{T}_{2}}}=\frac{271}{313-271}=6.4524\] \[{{(COP)}_{act}}=\frac{6.4524}{4}=1.613\] Worked required \[\frac{Q}{{{(COP)}_{act}}}=\frac{30}{1.613}=18.60\,\,kW\]You need to login to perform this action.
