Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe with a diameter of 0.5 m flowing at a Reynolds number of 400,000, calculate the wall shear stress if the fluid has a viscosity of 0.001 Pa.s.
💡 Hint: Utilize wall shear stress formulas and the relationships from Nikuradse’s experiments.
Question 2
If the flow in a non-circular conduit reaches a Reynolds number of 3 million, how might the viscous sublayer behave differently than in a lower Reynolds flow? Describe the consequences.
💡 Hint: Discuss the transitions observed in behavior as the Reynolds number increases.
