Challenge Problems
Push your limits with challenges.
Question 1
Design a trapezoidal canal for a specific flow rate. What dimensions will you choose if the desired flow is 20 m³/s, with a slope of 0.001?
💡 Hint: Use Manning's equation for velocity to back out area and then choose dimensions.
Question 2
Calculate the effect on the Froude number if the width of a trapezoidal channel is doubled while maintaining depth and flow.
💡 Hint: Remember the effect on A and its impact on flow dynamics.
