Description

Calculates saturated water/steam properties based on the steam tables, IF97 formulation (IAPWS-IF97).

Two calculation methods are available: from TT and xx or from PP and xx, where xx is the mass fraction, or vapor quality. For two-phase mixtures, properties are interpolated by quality:

h=x⋅hvap+(1−x)⋅hliqs=x⋅svap+(1−x)⋅sliqcp=x⋅cp,vap+(1−x)⋅cp,liqh = x \cdot h_{vap} + (1 - x) \cdot h_{liq} \\ \quad s = x \cdot s_{vap} + (1 - x) \cdot s_{liq} \\ \quad c_p = x \cdot c_{p,vap} + (1 - x) \cdot c_{p,liq}
