Challenge Problems
Push your limits with advanced challenges
A river has a width of 10m and a depth of 2m flowing at 5m/s. If a sluice gate reduces depth to 1m, calculate the new velocity and check if it transitions to supercritical.
💡 Hint: Apply v1 * y1 = v2 * y2 for A calculations.
Discuss how hydraulic jumps can affect the design of urban infrastructure and their implications for maintenance costs.
💡 Hint: Focus on environmental effects and engineering challenges.
