The image above represents viscosity. To calculate viscosity, four essential parameters are needed and these parameters are **Gram Molecular Weight (M), Temperature (Kelvin) (T), Characteristic Diameter (Ïƒ)** and** Collision Integral of Chapman Enskog Theory ( Î· _{n}).**

**The formula for calculating viscosity:**

Î· = ^{2.67E-5âˆš(MT)} / _{ÏƒÂ².Î·n}

Where:

Î· = Viscosity | Non Polar Gases

M = Gram Molecular Weight

T = Temperature (Kelvin)

Î» = Characteristic Diameter

Î·_{n} = Collision Integral of Chapman Enskog Theory

Let’s solve an example;

Find the viscosity when the gram molecular weight is 10, the temperature is 12, the characteristic diameter is 14 and the collision integral of chapman enskog theory is 16.

This implies that;

M = Gram Molecular Weight = 10

T = Temperature (Kelvin) = 12

Î» = Characteristic Diameter = 14

Î·_{n} = Collision Integral of Chapman Enskog Theory = 16

Î· = ^{2.67E-5âˆš(MT)} / _{ÏƒÂ².Î·n}

That is, Î· = ^{2.67E-5âˆš((10)(12))} / _{(14)Â².(16)}

Î· = ^{2.67E-5âˆš(120)} / _{(196).(16)}

Î· = ^{2.67E-5(10.954)} / _{3136}

So, Î· = ^{0.000292} / _{3136}

Î· = 9.326e-8

Therefore, the **viscosity **is **9.326e-8 mÂ²/s.**
