Question

For Non-Newtonian fluids, power law model consists parameter \( K \) known as

• A. Flow behaviour index
• B. Flow consistency index
• C. Viscosity
• D. Kinematic viscosity

Hint:

Power law fluids use consistency and behavior indices to define flow characteristics.

Answer 1

The Correct Option is B

In power law model: \( \tau = K \cdot \left( \frac{du}{dy} \right)^n \)
Here, \( K \) is the flow consistency index and \( n \) is the flow behavior index.
