Question 1
What happens to the velocity of fluid near the wall of a rough pipe?
- It remains constant
- It decreases to zero
- It increases
💡 Hint: Consider what it means for a fluid to 'stick' to a surface.
Question 2
True or False: The roughness of a pipe has no effect on turbulent flow.
- True
- False
💡 Hint: Think about how smooth and rough surfaces interact with fluids.

Challenge Problems
Push your limits with challenges.
Question 1
Given a rough pipe with a diameter of 15 cm, determine the average roughness if the velocity at 5 cm height from the wall is 50% more than at 2 cm.
💡 Hint: Refer to the logarithmic relationships discussed.
Question 2
You have two pipes: one smooth and one rough. How would you experimentally determine if the flow is turbulent in each?
💡 Hint: Visualizing the velocity distribution will provide insights.
