viscosity

pychemengg.physicalproperties.airproperties.viscosity(T=None)[source]

Provides viscosity of air at a temperature T

Parameters
Tint or float

Temperature in ‘Celsius’ at which viscosity (dynamic) is required.

Returns
Viscosity: int or float

Dynamic viscosity (kg/ms) at temperature T.

Notes

Look up table adapted from ref [1].

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