Challenge Problems
Push your limits with challenges.
Question 1
A rectangular channel has a width of 2 m and depth of 1 m. If the roughness coefficient n is 0.025 and the slope is 0.0015, what is the flow rate?
💡 Hint: Work through each step carefully, using the values provided.
Question 2
Consider a trapezoidal channel with a bottom width of 3 m, depth of 2 m, and side slopes of 1.5:1. If the slope is 0.002 and n = 0.030, find the flow rate.
💡 Hint: Break down the problem into calculating the area and perimeter separately before applying the equation.
