Challenge Problems
Push your limits with challenges.
Question 1
A rectangular channel with a width of 4m and depth of 3m is in use. Calculate the hydraulic diameter and the expected wall shear stress if the flow exhibits turbulent characteristics with a Reynolds number of 15,000.
💡 Hint: Ensure to consider how turbulent flow affects shear stress predictions.
Question 2
A pipe with a diameter of 0.1m has a flow rate of 0.01m³/s. Calculate the wall shear stress if the viscosity of the fluid is 1cP and the Reynolds number indicates turbulent flow.
💡 Hint: Pay attention to the flow regime to select the correct friction factor.
