Question

For a Non - Newtonian fluid, apparent viscosity depends on

• A. stress intensity
• B. proof stress
• C. velocity
• D. shear rate

Answer 1

Answer:

D. shear rate

Non-Newtonian fluids have a relation between shear stress and rate of deformation represented by $\tau=m(\frac{du}{dy})^n$ n=flow behavior index m = consistency index
