Default Sutherland law for Viscosity

Hi guys,

Quick question : for a case of an aircraft at 25000ft, the external static temperature is approximately 237Kelvin.

When I enter the viscosity in the materials panel, I chose the Sutherland 2 coefficient, with default values. From the Fluent manual however, the "moderate temperature and pressure" values are different that the default values in Fluent.

The 3-coefficient default values seems to correspond to those in the manual. Is it correct to use the 3-coef Sutherland equation with default values for this case?

Thanks Riaan
