2 cards from this section. Quick, good the night before a test.
Define hydraulic jump in your own words.
Think about changes in flow conditions and energy.
What is the Froude number for subcritical flow?
Recall how we define flow regimes.
What is the Froude number for supercritical flow?
Consider the definitions related to flow regimes.
Hydraulic jumps lead to what type of flow change?
Remember the key definition of a hydraulic jump.
A river has an upstream depth of 1.5m and a velocity of 6m/s. Calculate the downstream depth if the flow transitions from supercritical to subcritical. Use appropriate conservation principles.
Double-check flow conservation equations.
Design a spillway that minimizes energy loss during hydraulic jumps. Outline the critical parameters and considerations.
Think about specific engineering practices in spillway design.
