System for Clausius Inequality Proof Adapted from Fig:6-1 (C+B) Thermal Reservoir δQ R Tg Reversible Cyclic System δW rev δQ Combined System System δW sys © Copyright 2005 Prof. Arun S. Mujumdar.
Clausius Inequality (Cont’d) The system produces work δW sys as a result of this heat transfer. Applying the energy balance to the combined system identified by dashed lines yields: δW c = δQ r <strong>–</strong> dE c Where δW c is the total work of the combined system (δW rev + δW sys ) and dE c is the change in the total energy of the combined system. The cyclic device is a reversible one. © Copyright 2005 Prof. Arun S. Mujumdar. <strong>ME2121</strong> - Entropy I - Introduction (ASM) 19
