2 cards from this section. Quick, good the night before a test.
Define hydraulic jump in your own words.
Think about the physical change in flow properties.
What does a Froude number greater than 1 indicate?
Recall the definitions of flow classifications.
What occurs during a hydraulic jump?
Think about the flow speed and depth characteristics.
True or False: Energy loss during a hydraulic jump is always zero.
Consider the physical processes in a hydraulic jump.
A rectangular channel has a width of 1 m and carries a discharge of 0.8 m³/s at a depth of 0.4 m. Calculate the energy loss and sequent depth using the given data.
Break down the steps: area first, then velocity, followed by head loss calculation.
In a hydraulic jump, if the initial depth is 2 m, and flow speed is 6 m/s, calculate the sequent depth and energy loss if the Froude number is known.
Use formulas systematically to derive y2 from Fr1 and then calculate energy loss.
