Challenge Problems
Push your limits with challenges.
Question 1
Consider a pipe of diameter 0.2 m with a turbulent flow whose Reynolds number is 3000. Calculate the expected velocity profile near a rough section of the pipe.
💡 Hint: Employ the derived equations discussed during the lecture to guide your calculations.
Question 2
Evaluate how slight variations in roughness height can influence flow velocity in a rough-surfaced pipe with a known discharge rate. Find the impact of doubling the roughness height on flow characteristics.
💡 Hint: Focus on how friction loss is calculated in relation to roughness.
