Challenge Problems
Push your limits with advanced challenges
A hydraulic jump occurs when water with 5 m depth and 8 m/s velocity flows into a section with a depth of 2 m. Calculate the energy loss and discuss the implications of this jump.
💡 Hint: Remember to use the specific energy formula for both upstream and downstream.
Design a spillway section that minimizes hydraulic jumps while maintaining an effective flow. Consider specific energy calculations and the overall structure's impact.
💡 Hint: Evaluate flow profiles and transition areas.
