# Thermodynamic properties of heat carrier fluids

class PythonModel.fluids.ConstantPropertyWater

  Bases: `object`

  Object for the evaluation of thermal properties of heat transfer fluid Water.

  get_Density(**kwargs)

    Returns the density of water.

    Returns

      Density of water at 20 C (kg/m3)

    Usage: Type

          >>> flu = ConstantPropertyWater()
          >>> '%.2f' % flu.get_Density()
          '998.21'

  get_SpecificIsobaricHeatCapacity(**kwargs)

    Returns the specific isobaric heat capacity of water.

    Returns

      Specific isobaric heat capacity of water at 20 C (J/(kg.K))

    Usage: Type

          >>> flu = ConstantPropertyWater()
          >>> '%.2f' % flu.get_SpecificIsobaricHeatCapacity()
          '4184.05'

  get_SpecificVolume(**kwargs)

    Returns the specific volume of water.

    Returns

      Specific volume of water at 20 C (m3/kg)

    Usage: Type

          >>> flu = ConstantPropertyWater()
          >>> '%.8f' % flu.get_SpecificVolume()
          '0.00100180'

  modelicaModelPath()

    Returns the full path to the water model in the Buildings library.

    Returns

      Full path to the water model in the Buildings library.

    Note

    The minimum temperature is set to -50 C to avoid the Modelica model from failing.

    Usage: Type

          >>> flu = ConstantPropertyWater()
          >>> flu.modelicaModelPath()
          'Modelica.Media.Water.ConstantPropertyLiquidWater(T_min=223.15)'
