Challenge Problems

Push your limits with challenges.

Question 1

A trapezoidal channel has a bottom width of 8 meters and side slopes of 2:1. Given a flow depth of 2.5 meters, calculate the area, wetted perimeter, and discharge using Manning's equation.

💡 Hint: Pay attention to depth and slope when calculating.

Question 2

A circular pipe has a diameter of 1.2 meters and is flowing at a depth of 0.4 meters. Derive the area of flow, wetted perimeter, and evaluate the discharge rate. What if the diameter were reduced by half?

💡 Hint: Use trigonometric relationships for the circular portion.
