A) 0.5 k W
B) 0.67 k W
C) 1.5 k W
D) 3 k W
Correct Answer: A
Solution :
\[{{T}_{1}}\,\,=\,\,300\,K,\] \[{{T}_{2}}\,\,=\,\,200\,K\] \[COP=\frac{{{T}_{2}}}{{{T}_{1}}-{{T}_{2}}}=\frac{200}{300-200}=\frac{200}{100}=2\] \[=\,\,\frac{Q}{W}\,\,=\,\,\frac{1}{W}\] W=0.5 kWYou need to login to perform this action.
