To process this page used the WaterSteamPro function "wspT2APH": temperature in IF-97 region 2a [K] as function of pressure p [Pa], specific enthalpy h [J/kg].
Function is based upon additional equations of the IAPWS Industrial Formulation 1997 for Thermodynamic Properties of Water and Steam. Since at some stages the function use iterations, to speed up calculations you may disable precision mode (functions wspGETTOLERANCEMODE and wspSETTOLERANCEMODE) or vary relative precision for internal iterations (functions wspGETTOLERANCE and wspSETTOLERANCE).
