Optimal Design of Vapour Power Plant

Law of Nature for A Substance -1 Enthalpy Maxwell Relation Heat addition at constant pressure : Behavior of Vapour Economic creation of temperature Specific Heat :

Law of Nature for A Substance -2 Enthalpy Maxwell Relation Reversible nature of substance While creating a selected temperature. Treat as an isothermal heating process. Minimization of wastage during creation of temperature All these show that the irreversible behavior of a fluid decreased with increasing pressure.
