To process this page used the WaterSteamPro function "wspT5PS": temperature in IF-97 region 5 [K] as function of pressure p [Pa], specific entropy s [J/(kg·K)].
Function is based upon IAPWS Industrial Formulation 1997 for Thermodynamic Properties of Water and Steam. It uses the Newton method to determine the roots of the function with two arguments. 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).
