## Background for Sutherland Formula Viscosity Calculator Excel Spreadsheet

Sutherland’s formula for calculating the viscosity of a gas at a specified gas temperature is shown below along with an explanation of the parameters in the equation.

The parameters in Sutherland’s formula are as follows:

To = reference temperature, K

μo = viscosity of the gas at temperature, To

C = Sutherland’s constant for the gas, K

T = the temperature of the gas, K

μ = the viscosity of the gas at temperature, T, in the same units as μo.
