Two Carnot engines \(A\) and \(B\) are operated in series. The first one, \(A,\) receives heat at \(T_1(= 600\,K)\) and rejects to a reservoir at temperature \(T_2.\) The second engine \(B\) receives heat rejected by the first engine and, in turns, rejects to a heat reservoir at \(T_3 (=400\,K).\) Calculate the temperature \(T_2\) if the work outputs of the two engines are equal ..... \(K\)
- A \(600\)
- B \(400\)
- C \(300\)
- D \(500\)
Answer & Solution
Correct Answer
(D) \(500\)
Step-by-step Solution
Detailed explanation
\(W_1 = W_2\) \(\Rightarrow \,\,\,600-T_2\,=\,T_2\,-\,400\) \(\Rightarrow T_2\,=\,500\,K\)
