Challenge Problems
Push your limits with challenges.
Question 1
For a circular pipe with a diameter of 1 m, what is the hydraulic radius? Then compare this with a rectangular channel having a width of 2 m and depth of 1 m.
💡 Hint: Remember: diameter in circular channels relates differently to area and perimeter.
Question 2
Design a trapezoidal channel with a base width of 3 m, a depth of 2 m, and side slopes of 1:2. Calculate the hydraulic radius and explain its implications in flow dynamics.
💡 Hint: Break down the channel design into the base area and the lateral areas for easier computation.
