Challenge Problems
Push your limits with challenges.
Question 1
Calculate the turbulent shear stress in a pipe with a diameter of 0.5 m, flowing water at a velocity of 2 m/s with a Reynolds number indicating turbulent flow.
💡 Hint: You will need to assess the mixing length and gradient change for correct evaluation.
Question 2
Explain how you would apply Prandtl's mixing length theory to design a channel to optimize turbulent flow for better water distribution in irrigation systems.
💡 Hint: Think relationally about how distance from boundaries impacts flow behavior.
