Partial medium properties (base package of all media packages)
Extends from ThermalSeparation.Media.BaseMediumLiquidReaction (base class for liquid medium with reacting substances), Modelica.Icons.Package (Icon for standard packages).
Information
PartialMedium is a package and contains all declarations for a medium. This means that constants, models, and functions are defined that every medium is supposed to support (some of them are optional). A medium package inherits from PartialMedium and provides the equations for the medium. The details of this package are described in Modelica.Media.UsersGuide.
