The image above represents einstein relative apparent viscosity.

To compute for einstein relative apparent viscosity, one essential parameter is needed and these parameter is **Solid Landing (φ).**

The formula for calculating einstein relative apparent viscosity:

η_{ra} = 1 + 25φ

Where:

η_{ra} = Einstein Relative Apparent Viscosity

φ = Solid Landing

Let’s solve an example;

Find the einstein relative apparent viscosity when the solid landing is 24.

This implies that;

φ = Solid Landing = 24

η_{ra} = 1 + 25φ

η_{ra} = 1 + 25 x 24

η_{ra} = 1 + 600

η_{ra} = 601

Therefore, the **einstein relative apparent viscosity **is **601.**

**Calculating for Solid Landing when the Einstein Relative Apparent Viscosity is Given.**

φ = ^{ηra – 1} / _{25}

Where;

φ = Solid Landing

η_{ra} = Einstein Relative Apparent Viscosity

Let’s solve an example;

Given that the einstein relative apparent viscosity is 56. Find the Solid landing?

This implies that;

η_{ra} = Einstein Relative Apparent Viscosity = 56

φ = ^{ηra – 1} / _{25}

φ = ^{56 – 1} / _{25}

φ = ^{55} / _{25}

φ = 2.2

Therefore, the **solid landing **is **2.2.**
