Challenge Problems
Push your limits with challenges.
Question 1
A rectangular channel has an upstream flow with a depth of 3m and velocity of 4m/s. Calculate the flow depth after a hydraulic jump and the energy loss.
💡 Hint: Use the mass conservation principle to derive downstream conditions.
Question 2
Design a trapezoidal channel with a specific discharge requirement. What dimensions would minimize the perimeter?
💡 Hint: Remember that you're solving for minimum dimensions under fixed discharge.
