The image above represents viscosity of pseudoplastic fluids.

To compute for viscosity of pseudoplastic fluids, three essential parameters are needed and these parameters are **Flow Index (n), Shear Rate (γ)** and **Consistency (η _{p}).**

The formula for calculating viscosity of pseudoplastic fluids:

η_{o} = η_{p} γ^{n – 1}

Where:

η_{o} = Viscosity of Pseudoplastics Fluids

n = Flow Index

γ = Shear Rate

η_{p} = Consistency

Let’s solve an example;

Find the viscosity of pseudoplastic fluids when the flow index is 20, the shear rate is 14 and the consistency is 10.

This implies that;

n = Flow Index = 20

γ = Shear Rate = 14

η_{p} = Consistency = 10

η_{o} = η_{p} γ^{n – 1}

η_{o} = 10 x 14^{20 – 1}

η_{o} = 10 x 14^{19}

η_{o} = 10 x 5.97e+21

η_{o} = 5.97

Therefore, the **viscosity of pseudoplastic fluids **is **5.97 e+22.**
