Dynamic viscosity


Pressure: Pa

Specific enthalpy: J/kg

Dynamic viscosity: 1,4221415060401E-03 Pa·sec


To process this page used the WaterSteamPro function "wspDYNVISPH": dynamic viscosity [Pa·sec] as function of pressure p [Pa], specific enthalpy h [J/kg].

The range of the validity is within that described in IF-97 and in formulation for dynamic viscosity (see function wspDYNVISRT). The function wspWATERSTATEAREAPH is used to determine the IF-97 region. Then the necessary function (wspTxPH) is used. Finally, the necessary function (wspDYNVISPT or wspDYNVISSTX) is called. 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).
