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)));

state = setState_dTX(d, T, X, phase)

d	Type: Density (kg/m³) Description: Density
T	Type: Temperature (K) Description: Temperature
X	Default Value: reference_X Type: MassFraction[:] (kg/kg) Description: Mass fractions
phase	Default Value: 0 Type: FixedPhase Description: 2 for two-phase, 1 for one-phase, 0 if not known

state	Type: ThermodynamicState Description: Thermodynamic state record
