Question

Derive the chambadal-novikov equation

Answer 1

$\frac{QH}{THW}=\frac{QC}{TCW}$ is fulfilled in this cycle. Only the entropy produced during the exchange of heat between the system and its reservoirs is considered. Substance working temperatures are THW and TCW, resulting in TCWTH. In contrast, the Carnot efficiency is attained when the reservoir temperatures are the same as the engine temperatures, which implies THW=TH and TC=TCW in Figure 1.

$ηC=1−TCTH=1−TCWTCH$

 This is the chambadal-novikov equation
