Joule-Thomson coefficient


Pressure: Pa

Temperature: K

Vapor fraction:

Joule-Thomson coefficient: 6,63314170760519E-05 K/Pa


To process this page used the WaterSteamPro function "wspJOULETHOMPSONPTX": joule-Thomson coefficient [K/Pa] as function of pressure p [Pa], temperature t [K], vapor fraction x [-].

The range of the validity is within that described in IF-97. The function wspWATERSTATEAREA is used to determine the IF-97 region. Then the necessary function (wspJOULETHOMPSONPT or wspJOULETHOMPSONSTX) is used. If the point is out of the double-phase area the value of vapor fraction is ignored.
