Challenge Problems

Push your limits with challenges.

Question 1

A water pipe has a diameter reduction that causes internal pressure to change. Analyze the stress tensor at two points before and after the reduction and how it impacts the fluid flow.

💡 Hint: Consider both shear and normal stress components in the calculations.

Question 2

Using Cauchy's equations, derive a specific case for a viscous fluid passing through a narrow channel and discuss the implications for flow rate.

💡 Hint: Review how viscosity factors into Cauchy’s equations under flow conditions.
