There are two classical statements of the second law of thermodynamics (the Kelvin–Plank and Clausius statements). Can there be other valid statements? If so, why are these classical definitions repeated in almost every thermodynamics textbook? Can you determine if a process is possible by performing an entropy analysis? Explain. The first law of thermodynamics is also known as the conservation of energy principle and leads to energy balances. Is there a corresponding entropy balance or exergy balance?
33) For heat transfer across a region r on a control surface for which the temperature may vary, ExQ = [qr (1 − To /Tr )dAr ] r where qr is the heat flow per unit area at a region on the control surface at which the temperature is Tr . 34) Exergy: Energy, Environment and Sustainable Development 28 1 0 5 τ 10 15 T To Ϫ1 Ϫ2 Ϫ3 Fig. 1.

1. Illustrative example 1 A heat source at 800 K loses 2000 kJ of heat to a sink at (a) 500 K and (b) 750 K. Determine which heat transfer process is more irreversible. Solution: A sketch of the reservoirs is shown in Fig. 3. Both cases involve heat transfer through a finite temperature difference and are therefore irreversible. The magnitude of the irreversibility associated with each process can be determined by calculating the total entropy change for each case. The total entropy change for a heat transfer process involving two reservoirs (a source and a sink) is the sum of the entropy changes of each reservoir since the two reservoirs form an adiabatic system.
