A) 180 k W
B) 30 k W
C) 6 k W
D) 5 k W
Correct Answer: A
Solution :
\[{{T}_{1}}=273+27=300\,\,K,\] \[{{T}_{2}}=273-23=250\,K\] \[{{(COP)}_{HP}}=\frac{{{T}_{1}}}{{{T}_{1}}-{{T}_{2}}}=\frac{300}{300-250}=\frac{300}{50}=6=\frac{W}{Q}\] \[W\,\,=\,\,30\,\,\times \,\,6\,\,=\,\,180\,\,k\,W\]You need to login to perform this action.
