To process this page used the WaterSteamPro function "wspPRANDTLEPT": prandtl number [-] as function of pressure p [Pa], temperature t [K].
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. The equation is: Pr = DYNVIS · CP / THERMCOND is used for calculation, where DYNVIS is calculated by the function wspDYNVISPT, CP - by wspCPPT and THERMCOND - by wspTHERMCONDPT.
