This is Part – IV of the book: “Basic Thermodynamics: Software Solutions”.
Here, Availability or ‘Exergy’, Irreversibility and Second Law analysis of systems are dealt with.
Several useful EES Functions are written for Exergy under various conditions and for closed systems and when there is a mass flow, for Ideal gases as well as real fluids. EES Functions are also written for entropy changes for various processes. Use of these Functions in problem solving is demonstrated.
Exergy balance and II Law analysis of systems is explained.
Above topics are illustrated by solving several problems using Mathcad, EES and TEST software.
