To process this page used the WaterSteamPro function "wspCPPTX": specific isobaric heat capacity [J/(kg·K)] as function of pressure p [Pa], temperature t [K], vapor fraction x [-].
The range of the validity is within that described in IF-97. The function wspWATERSTATEAREA is used to determine the IF-97 region. Then the necessary function (wspCPxPT or wspCPSTX) is used. If the point is out of the double-phase area the value of vapor fraction is ignored.
