Question 1
Given a trapezoidal channel described with specific dimensions and slope, derive the best cross-section for maximum efficiency.
💡 Hint: Use calculus for optimization: dA/dP set to zero reflects maximum efficiency conditions.
Question 2
For a circular section with varying depths, determine the angle θ that yields maximum discharge using Manning’s approach.
💡 Hint: Quadratic solutions might yield depths that equate to maximum velocity.
