Density of the StandardWater - Modelica

How can I know what is the density of the Medium of StandardWater used in Modelica? With which function can I directly specify the density of the StandardWater?

Solution

  • First, instantiate the medium package in your model, e.g.

    package Medium = Modelica.Media.Water.StandardWater;

    Then, create a thermodynamic state, given e.g. pressure/temperature or pressure/enthalpy;

    Medium.ThermodynamicState state = Medium.setState_pT(p=2e5, T=80+273.15);

    And, finally, look up the density with the state

    Medium.Density rho = Medium.density(state);
