Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical pipe has a radius of 0.05 m and a shear stress at the wall of 50 N/m². Calculate the frictional velocity and discuss the implications of this value on flow rate.
💡 Hint: Use the given shear stress to find the relation.
Question 2
Discuss the effects of reducing surface roughness in piping systems in terms of turbulent flow efficiency.
💡 Hint: Consider how rough surfaces affect flow interaction.
