Challenge Problems
Push your limits with challenges.
Question 1
Calculate the discharge for a trapezoidal channel with a bottom width of 8m, depth of 2m, and a side slope of 1:2. Given n = 0.015 and S₀ = 0.002.
💡 Hint: Break it into steps: Area first, then perimeter, finally use Manning's equation.
Question 2
For a circular pipe with a diameter of 1.0m and flow depth of 0.4m, calculate the discharge using n = 0.013 and S₀ = 1/1000.
💡 Hint: Focus on finding theta to determine the submerged area.
