Challenge Problems
Push your limits with challenges.
Question 1
Design a simple experiment for measuring wall shear stress in a circular pipe and explain the necessary components.
💡 Hint: Consider experimental design elements and flow measurement techniques.
Question 2
Consider two noncircular conduits: one is a semi-circular and the other a rectangular. How would you compute their hydraulic diameters, and what potential flow characteristics do you expect?
💡 Hint: Use area and perimeter measurements specific to those shapes.
