Analysis of the adiabatic process by using the thermodynamic property diagram of water vapor

In the steam power plant, working medium used for energy transformation is water vapor. The thermodynamic properties of vapor are usually obtained by using tables and charts. Adiabatic process widespread in engineering applications. adiabatic realized without heat addition or rejection entropy during a reversible remains constant. During an expansion process, superheated turns into saturated , further wet vapor, pressure temperature decreases. irreversible increases. general, when analyzing we first determine state parameters charts tables, then make relevant calculations according to law thermodynamics.
