This is where Wark outshines his peers. He introduces entropy via the Clausius inequality with exceptional clarity. The 2021 relevance? As we focus on green energy and heat pump efficiency, Wark’s sections on Carnot cycles and entropy generation have aged perfectly.
Pro tip: In your PDF, bookmark the "Entropy Balance" equation box on page 320 (varies by edition). Refer to it for every cycle analysis.
