Properties calculation result in IF-97 region 1

Density: kg/m3

Specific enthalpy: J/kg

Properties calculation result in IF-97 region 1: 1

Pressure: Pa

Temperature: K

To process this page used the WaterSteamPro function "wspPT1RH": properties calculation result in IF-97 region 1 as function of density r [kg/m3], specific enthalpy h [J/kg].

Function is based upon IAPWS Industrial Formulation 1997 for Thermodynamic Properties of Water and Steam. The function uses the Newton method to determine the roots. 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).
