Challenge Problems
Push your limits with advanced challenges
You are tasked to design a non-circular conduit for a city water supply. How would you approach the determination of hydraulic diameter and wall shear stress?
💡 Hint: Consider if the pipe will operate in laminar or turbulent conditions.
A flow in a triangular pipe exhibits a non-uniform velocity profile. Explain how you would determine the wall shear stress for this scenario.
💡 Hint: Relate back to the discussion on laminar vs turbulent flow.
