Specific internal energy


Pressure: Pa

Temperature: K

Vapor fraction:

Specific internal energy: Error: 1. Bad function parameters. It is error occured while calculating with given parameters. J/kg


To process this page used the WSP function "wspUPTX": specific internal energy [J/kg] 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 (wspUxPT or wspUSTX) is used. If the point is out of the double-phase area the value of vapor fraction is ignored.
