Calculate the steam quality (vapor fraction) as a function of pressure (P in kPa) and enthalpy (H in J/g). Use only for wet steam. By default, input arguments and returned values are in SI units. You can change the units of measure, for example, by using the Convert function.
Syntax
Steam_XPH(P, H)
Arguments
-
P
Pressure of the steam. P can range from 0.611212678 to 22064 kPa.
-
H
Enthalpy of the steam. H can range from -0.04159 to 4160.7 J/g.
Returns
Computed steam quality (vapor fraction)
Example
-
Steam_XPH(10000, 2500)
[Returns 0.82888]
