Prandtl number in double-phase area

Temperature: K

Vapor fraction:

Prandtl number in double-phase area: Error: 2. Parameters are out of range.

To process this page used the WSP function "wspPRANDTLESTX": prandtl number in double-phase area [-] as function of temperature t [K], vapor fraction x [-].

Function uses functions wspPRANDTLESST and wspPRANDTLESWT which returns Prandtl numbers of steam and water at saturation line. The function uses following formula: PRANDTLEx = (1 - X)·PRANDTLEw + X·PRANDTLEs, where PRANDTLEs = wspPRANDTLESST, PRANDTLEw = wspPRANDTLESWT and X - vapor fraction. The range of calculation is double-phase (water-vapor) area.
