Isothermal compressibility as a function of temperature and pressure (β)

Information

For an ideal gas, this function is independent of temperature (although temperature remains as a valid input).

Interface

function beta
  extends Modelica.Icons.Function;
  input Q.TemperatureAbsolute T = 298.15*U.K "Temperature" annotation(
    Dialog(__Dymola_label = "<html><i>T</i></html>"));
  input Q.PressureAbsolute p = p0 "Pressure" annotation(
    Dialog(__Dymola_label = "<html><i>p</i></html>"));
  output Q.PressureReciprocal beta "Isothermal compressibility";
end beta;
