CLAUSIUS INEQUALITY AND ENTROPY

RANKINE POWER GENERATION CYCLE

Significance: area enclosed by process lines equals the net heat transfer by Clausius’ Principle for internally reversible processes: dQ = TdS for a cycle: net =∫Q TdS and by the First Law for a cycle: Qnet = Wnet Wturbine + Wpump = QH + QL where Wturbine is positive, Wpump is negative, QH is positive, QL is negative,

The devices or systems used to produce a net power output are often called engines and the thermodynamics cycles they operate on are called power cycle. The devices or systems use to produce refrigeration are called refrigerator, air conditioners or heat pumps and the cycles they operates on are called refrigeration cycles.
