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.**
