To process this page used the WaterSteamPro function "wspVSTX": specific volume in double-phase area [m3/kg] as function of temperature t [K], vapor fraction x [-].
Function uses the functions wspVSST and wspVSWT which return specific volumes of steam and water at saturation line. The function uses following formula: Vx = (1 - X)·Vw + X·Vs, where Vs = wspVSST, Vw = wspVSWT and X - vapor fraction. The range of validity is double-phase (water-vapor) area.
