Pressure in IF-97 region 3


Specific enthalpy: J/kg

Specific entropy: J/(kg·K)

Pressure in IF-97 region 3: 50299269,4779537 Pa


To process this page used the WaterSteamPro function "wspP3HS": pressure in IF-97 region 3 [Pa] as function of specific enthalpy h [J/kg], specific entropy s [J/(kg·K)].

Function is based upon "Supplementary Release on Backward Equations for p(h, s) for Region 3, Equations as a Function of h and s for the Region Boundaries, and a Equation Tsat(h, s) for Wet Steam of the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam" (September 2004). 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).
