A Carnot engine whose efficiency is 40% takes in heat from source maintained at a temperature of 500 K. It is desired to have an
engine of efficiency 60%. Then, the intake temperature for the same exhaust (sink) temperature must be
- A 1200 K
- B 750 K
- C 600 K
- D 800 K
Answer & Solution
Correct Answer
(B) 750 K
Step-by-step Solution
Detailed explanation
Efficiency of Carnot engine, \(\eta_1=40 \%=0.4\) Temperature of source \(T_1=500 \mathrm{~K}\) Temperature of \(\operatorname{sink} T_2=T\) Desired efficiency, \(\eta_{\varepsilon}=60 \%=0.6\) Temperature of \(\operatorname{sink} T_2=T\) Temperature of source \(T_1=\) ? For…
