Challenge Problems
Push your limits with challenges.
Question 1
A trapezoidal channel has a bottom width of 6 m, a slope of 2:1, and an n value of 0.025. What slope must the channel have to carry a discharge of 150 cubic meters per second at a depth of 4 m?
💡 Hint: Don’t forget to check your area and perimeter calculations.
Question 2
In a circular pipe with an diameter of 1.2 m flowing full, estimate the maximum discharge coefficient if its n value is 0.015 and it is inclined at 1 in 800.
💡 Hint: You may need to find the hydraulic radius prior to plugging values into the equation.
