Viscosity of Air Calculator

Enter the temperature of the air into the calculator to determine the viscosity.

Viscosity of Air Formula

The following formula can be used to calculate the viscosity of air.

u = ( b * T^(3/2)) / (T+S)

  • Where u is the viscosity
  • b is a constant (1.458 x 10^-6)
  • T is the temperature (Kelvin)
  • S is another constant (110.4)

Viscosity of Air Definition

The viscosity of air is defined as the air gasses resistance to flow and is dependent solely on the temperature.

Viscosity of Air Example
