Vapor fraction

Temperature: K

Prandtl number:

Vapor fraction: Error: 2. Parameters are out of range.

To process this page used the WaterSteamPro function "wspXSTPRANDTLE": vapor fraction [-] as function of temperature t [K], Prandtl number pr [-].

This function uses formula: X = (PR - PRw)/(PRs - PRw), where PRw = wspPRANDTLESWT, PRs = wspPRANDTLESST. The range of calculation is double-phase (water-vapor) area.
