Calculate the specific enthalpy as a function of pressure (P in kPa) and quality (vapor fraction). 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_HPX(P, X)
Arguments
-
P
Pressure of the steam. P can range from 0.611212678 to 22064 kPa.
-
X
Steam quality (vapor fraction). X can range from 0.0 to 1.0.
Returns
Computed specific enthalpy in J/g.
Example
-
Steam_HPX(10000, 0.9)
[Returns 2593.7 J/g]
