Pressure in IF-97 region 2


Specific enthalpy: J/kg

Specific entropy: J/(kg·K)

Pressure in IF-97 region 2: 1371011,80012643 Pa


To process this page used the WaterSteamPro function "wspP2HS": pressure in IF-97 region 2 [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 Pressure as a Function of Enthalpy and Entropy p(h,s) to the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam" (September 2001) and used the functions: wspP2AHS(h, s), wspP2BHS(h, s) and wspP2CHS(h, s). 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).
