A) 12
B) 4.8
C) 3.5
D) 1.6
Correct Answer: A
Solution :
[a] Efficiency \[=\frac{{{T}_{1}}-{{T}_{2}}}{{{T}_{1}}}\] \[{{T}_{1}}=227+273=500\,K\] \[{{T}_{2}}=127+273=400\,K\] \[\eta =\frac{500-400}{500}=\frac{1}{5}\] Hence, \[V=(\eta )\times H=\frac{1}{5}\times 6=1.2\,\,k\,cal\]You need to login to perform this action.
