Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Although the medium package is explicit for pressure and specific enthalpy, this function may be used in order to calculate the thermodynamic state record used as input by many functions. It will calculate the missing states:
- pressure
- specific enthalpy
Example:
parameter Medium.Density d = 4; parameter Medium.Temperature T = 298; Medium.SpecificEntropy s; equation s = Medium.specificEntropy(setState_dTX(d, T, fill(0, Medium.nX)));
Syntax
state = setState_dTX(d, T, X, phase)
