To process this page used the WaterSteamPro function "wspTHERMCONDPS": thermal conductivity coefficient [W/(m·K)] as function of pressure p [Pa], specific entropy s [J/(kg·K)].
The range of the validity is within that described in IF-97 and in formulation for thermal conductivity (see function wspTHERMCONDRT). The function wspWATERSTATEAREAPS is used to determine the IF-97 region. Then the necessary function (wspTxPS) is used. Finally, the necessary function (wspTHERMCONDPT or wspTHERMCONDSTX) 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).
