Water-Steam Mollier Diagram

Enthalpy-entropy diagram for water and steam.

Dryness Fraction

The quantity of saturated vapor in unit mass of wet vapor, denoted by x, is referred to as the

dryness fraction, or quality,

of the vapor.

Convert to other Units

1 bar = 10⁵ Pa (N/m²) = 0.1 N/mm² = 10,197 kp/m² = 10.20 m H₂O = 0.9869 atm = 14.50 psi (lb_f/in²) = 10⁶ dyn/cm² = 750 mmHg
1 kJ/kg = 0.4299 Btu/ lb_m = 0.23884 kcal/kg

Example - Enthalpy

The enthalpy in saturated steam (x = 1, the bold red line in the diagram) with pressure 10 bar can be estimated to aprox.

2770 kJ/kg

The value can be verified by using the steam table.
