pyiapws95.wagner.water_props¶

pyiapws95.wagner.water_props(pressure: float, temperature: float, density: float) → Optional[Tuple[float, float, float, float, float, float, float, float, float, float]][source]¶

Computes water properties.

Implements formulas from table 6.3 in Wagner and Pruss

Parameters

pressure (float) – Pressure [Pa]
temperature (float) – Temperature [K]
density (float) – Initial density [kg/m^3]

Returns

Calculated values: ‘temperature’, ‘pressure’, ‘density’, ‘entropy’, ‘internal_energy’, ‘enthalpy’, ‘gibbs_free_energy’, ‘isochoric_heat_capacity’, ‘isobaric_heat_capacity’, ‘speed_of_sound’. When iteration fails to converge None is returned.

Return type

tuple or None
