The Sutherland's viscosity law for gases has been derived from the kinetic theory by
Sutherland using an idealized intermolecular-force potential. It is given as:
CT3/2
where u is the viscosity, C and S are empirical constants, and T is the absolute
temperature.
Following is the viscosity data for air at different temperatures.
