To process this page used the WaterSteamPro function "wspJOULETHOMPSON1PT": joule-Thomson coefficient in IF-97 region 1 [K/Pa] as function of pressure p [Pa], temperature t [K].
Function is based upon the IAPWS Industrial Formulation 1997 for Thermodynamic Properties of Water and Steam. The equation: JT = (T*dV/dT - V)/Cp is used, where T - temperature, dV/dT - differential quotient (dV/dT)p, V - volume, Cp - isobaric heat capacity (Cp).
