Challenge Problems
Push your limits with advanced challenges
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.
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.
