heatofvaporization¶

pychemengg.physicalproperties.waterliquidproperties.heatofvaporization(T=None)[source]¶

Provides heat of vaporization of liquid water at a temperature T.

Parameters

Tint or float: Temperature in ‘Celsius’ at which heat of vaporization is required.

Returns

Heat of vaporizationint or float: Heat of vaporization (J/kg) at temperature T.

Notes

Look up table adapted from ref [1].

Linear interpolation is performed when the temperature lies between tabulated entries.
