To process this page used the WaterSteamPro function "wspKSTX": isoentropic exponent in double-phase area [-] as function of temperature t [K], vapor fraction x [-].
Function calculate isoentropic exponent in double-phase area considering property jump at saturation line. Until version 5.6 this function uses following formula: Kx = (1 - X)·Kw + X·Ks, where Ks = wspKSST, Kw = wspKSWT and X - vapor fraction. But that is not agree with thermodynamic. Now it is calculated properly. The range of validity is double-phase (water-vapor) area.
