Chapter 8  Exergy: A measure of work potential. In this chapter, we examine the performance of engineering devices in light of the second law of thermodynamics. We start our discussions with the introduction of exergy (also called availability), which is the maximum useful work that could be obtained from the system at a given state in a specified environment, and we continue with the reversible work, which is the maximum useful work that can be obtained as a system undergoes a process between two specified states.
