This base properties model is identical to
    
    Modelica.Media.Water.ConstantPropertyLiquidWater,
    except that the equation
    u = cv_const*(T - reference_T)
    has been replaced by u=h because
    cp_const=cv_const.
    Also, the model checks if the mass fraction of the mixture is within the
    allowed limits.
