The above derivation did not utilize the details of the four-step cycle that comprises the Carnot engine. However, the net work and net heat of the cycle in Fig. 4.2 given by Eqs (4.1) and (4.2) result in the efficiency of Eq (4.6). (prob. 4.22)

Demonstration that the Carnot engine has the maximum possible efficiency is based on the pair of engines shown in Fig. 4.8. The method posits a higher efficiency
