Question

In non-Newtonian fermentation broths, the flow behavior index (n) < 1 indicates:

• A. Newtonian fluid
• B. Pseudoplastic fluid
• C. Dilatant fluid
• D. Bingham plastic fluid

Hint:

Pseudoplastic fluids exhibit shear-thinning behavior, which is important in understanding the flow of fermentation broths.

Answer 1

The Correct Option is B

For a non-Newtonian fluid, a flow behavior index (n) less than 1 indicates pseudoplastic behavior, where the fluid viscosity decreases with increasing shear rate. This behavior is common in many fermentation broths.
