Challenge Problems
Push your limits with challenges.
Question 1
Design a rectangular channel to carry a flow rate of 100 m³/s with a minimum construction cost. What dimensions would you choose?
💡 Hint: Use calculus to find minimum perimeter related to area.
Question 2
Explain how you would calculate the energy losses for a hydraulic jump that transitions from an upstream depth of 3 meters, velocity 8 m/s to a downstream depth of 2 meters. Include Froude number calculation.
💡 Hint: Use E = y + v²/(2g) to compute energies.
