The image above represents relative apparent viscosity (for concentrated suspension).

To compute for relative apparent viscosity (for concentrated suspension), three essential parameters are needed and these parameters are **Intrinsic Viscosity (η _{i}), Solid Landing (φ)** and

**Maximum Solid Landing (φ**

_{m}).The formula for calculating relative apparent viscosity (for concentrated suspension):

η_{ra} = (1 – ^{φ} / _{φm})^{-(ηi)φm}

Where:

η_{ra} = Relative Apparent Viscosity

η_{i} = Intrinsic Viscosity

φ = Solid Landing

φ_{m} = Maximum Solid Landing

Let’s solve an example;

Find the relative apparent viscosity when the intrinsic viscosity is 20, the solid landing is 32 and the maximum solid landing is 12.

This implies that;

η_{i} = Intrinsic Viscosity = 20

φ = Solid Landing = 32

φ_{m} = Maximum Solid Landing = 12

η_{ra} = (1 – ^{φ} / _{φm})^{-(ηi)φm}

η_{ra} = (1 – ^{32} / _{12})^{-(20) x 12}

η_{ra} = (1 – 2.66)^{-240}

η_{ra} = (-1.66)^{-240}

η_{ra} = **5.705e-54**

Therefore, the **relative apparent viscosity (for concentrated suspension) **is **5.705e-54.**
