Joule-Thomson coefficient in IF-97 region 3

To process this page used the WaterSteamPro function "wspJOULETHOMPSON3PT": joule-Thomson coefficient in IF-97 region 3 [K/Pa] as function of pressure p [Pa], temperature t [K].

Function calculates Joule-Thomson coefficient for region 3 of IF-97 Formulation. This function uses function wspR3PT(p, t) to calculate density and then returns the value from the function wspJOULETHOMPSON3RT(r, t). 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).
