2 cards from this section. Quick, good the night before a test.
What does a Froude number less than 1 indicate?
Remember the classification of flows.
What is the term used to describe energy loss during a hydraulic jump?
It's the difference in specific energy.
What does a Froude number greater than 1 indicate?
Think about velocity in relation to surface waves.
Is energy loss during a hydraulic jump always present?
Recall the nature of the flow transition.
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.
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.
Evaluate flow profiles and transition areas.
