Practice Questions

Question 1

In the context of non-Newtonian fluids, what does the term 'yield stress' refer to?

Question 2

Which of the following viscosity models is most appropriate for a fluid that exhibits both yield stress and shear-thinning behavior?

Question 3

When designing equipment for processing shear-thickening fluids, which of the following considerations is most critical?

Question 4

Consider a fluid described by the power law model: $\tau = K(\dot{\gamma})^n$. If the fluid is shear-thickening, what is the typical range for the power law index $n$?

Question 5

In the context of non-Newtonian fluids, how does the apparent viscosity of a shear-thickening fluid change with an increase in shear rate?
