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.
