Information

Function to compute the water vapor concentration based on saturation pressure, absolute pressure and relative humidity.

Interface

function X_pSatpphi
  extends Modelica.Icons.Function;
  input Modelica.SIunits.AbsolutePressure pSat "Saturation pressure";
  input Modelica.SIunits.Pressure p "Pressure of the fluid";
  input Real phi(min = 0, max = 1) "Relative humidity";
  output Modelica.SIunits.MassFraction X_w(min = 0, max = 1, nominal = 0.01) "Water vapor concentration per total mass of air";
end X_pSatpphi;
