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 IBPSA library.

Returns:	Full path to the water model in the IBPSA 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)'
