To process this page used the WSP function "wspPRANDTLEPTX": prandtl number [-] as function of pressure p [Pa], temperature t [K], vapor fraction x [-].
The range of the validity is within that described in IF-97 and in formulations for the properties included in the equation to calculate sought quantity (see function wspPRANDTLEPT, wspTHERMCONDRT, wspDYNVISRT). The function wspWATERSTATEAREA is used to determine the IF-97 region. Then the necessary function (wspPRANDTLEPPT or wspPRANDTLEPSTX) is used. If the point is out of the double-phase area the value of vapor fraction is ignored.
