Challenge Problems
Push your limits with challenges.
Question 1
A pipe carries water at high velocity leading to turbulent flow. Discuss how eddy viscosity would compare to dynamic viscosity in this scenario.
💡 Hint: Consider how turbulence at high speeds increases momentum transfer.
Question 2
Derive the approximate relationship of turbulent shear stress in a pipe using Prandtl's mixing length theory and suggest improvements for engineering design.
💡 Hint: Think of ways to implement this theory practically to reduce energy losses in pipelines.
