Vapor fraction


Temperature: K

Specific isobaric heat capacity: J/(kg·K)

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


To process this page used the WaterSteamPro function "wspXSTCP": vapor fraction [-] as function of temperature t [K], specific isobaric heat capacity Cp [J/(kg·K)].

This function uses formula: X = (CP - CPw)/(CPs - CPw), where CPw = wspCPSWT, CPs = wspCPSST. The range of calculation is double-phase (water-vapor) area.
