thermalconductivity

pychemengg.physicalproperties.airproperties.thermalconductivity(T=None)

Provides thermal conductivity of air at a temperature T.

Parameters

Tint or float

Temperature in ‘Celsius’ at which thermal conductivity is required.

Returns

Thermal conductivityint or float

Thermal conductivity (W/mK) at temperature T.

Notes

Look up table adapted from ref [1].

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