functionsaturationPressure
Saturation curve valid for 223.16 <= T <= 373.16 (and slightly outside with less accuracy)
Extends from Modelica.Icons.Function (Icon for functions).
Information
Saturation pressure of water, computed from temperature, according to Wagner et al. (1993). The range of validity is between 190 and 373.16 Kelvin.
