Wet saturated steam -  thermodynamics:

wet saturated steam Wet steam is a 2-phase mixture comprising of boiling water particles and dry steam in equilibrium state. Its formation begins when water is heated beyond its boiling point, thereby initiating evaporation. A wet steam exists in different proportions of water particles and dry steam. Accordingly, the qualities of it are also different. Quality of wet steam can be expressed in terms of dryness fraction which is explained below.
