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.

Air Viscosity Calculator Pressure Temperature Spreadsheet Applications
An Air Viscosity calculator pressure temperature excel spreadsheet can be used for any situation where a value of air viscosity is needed at a specified pressure and temperature. This could include calculations for air flow in a pipe, drag force or drag coefficient calculations for flow of an object through air, and any other calculation requiring the Reynolds number for air flow or flow through air. For example, see the related article, Fanno Flow Excel Spreadsheet for Air Flow in a Pipe.
Equations for an Air Viscosity Calculator Pressure Temperature Spreadsheet
Equations are available for an air viscosity temperature calculator to calculate the viscosity of air at specified temperature and pressure. The spreadsheet shown in the diagram below calculates air density using an equation for air viscosity as a function of temperature ratio, T_{r} , and density ratio, ρ_{r} , where in U.S. units: T_{r }= _{ }T/238.5 with T in degrees R and ρ_{r }= ρ/0.6096 with ρ in slugs/ft^{3}. Since the air density is needed for this calculation, the spreadsheet also calculates the density of air at the specified air temperature and pressure. The complete equations are included in the spreadsheet discussed above and shown in the screenshot below.
