Challenge Problems
Push your limits with challenges.
Question 1
A trapezoidal channel has a bottom width of 4 m, side slopes of 2:1, and a depth of 3 m. Calculate the hydraulic radius.
💡 Hint: Use the trapezoid area formula and remember to find both the area and perimeter carefully.
Question 2
Compare the energy loss in a long rectangular channel with laminar flow versus turbulent flow. Discuss factors impacting these losses.
💡 Hint: Consider the nature of flow and how it interacts with the channel surface.
