# .BuildSysPro.IBPSA.Media.Specialized.Water.ConstantProperties_pT

Package with model for liquid water with constant properties at user-provided nominal conditions

## Information

Model for liquid water with constant properties at given nominal conditions.

This water model is similar to IBPSA.Media.Water with regard to its complexity. It also uses constant values for properties such as density and specific heat capacity. The main difference is that the constants `T_nominal` and `p_nominal` allow for user-provided nominal condition of the water model. The constant properties will be derived for this nominal condition. The maximum allowed temperature is set at the saturation temperature for the given nominal pressure `p_nominal`.

#### Assumptions and limitations

The nominal values for the constant medium properties are calculated using the Modelica.Media.Water.WaterIF97_base model.

#### Typical use and important parameters

A model using this medium model can set the nominal conditions e.g. by defining

      package Medium = IBPSA.Media.Specialized.Water.ConstantProperties_pT(
        T_nominal=273.15+100,
        p_nominal=5e5);
