3 cards from this section. Quick, good the night before a test.
Define the Froude number.
Think about its relationship with gravity and fluid velocity.
What happens during a hydraulic jump?
Remember the role of velocity in flow conditions.
What is a hydraulic jump?
Consider the characteristics of supercritical versus subcritical flow.
True or False: The Froude number can only be greater than one.
Think about the implications of flow regimes.
A rectangular channel with a width of 2 meters and a flow rate of 3 m³/s has a depth of 0.5 m. Find the Froude number at this depth and determine if a hydraulic jump is likely.
Use the Q and A to find velocity first!
Consider a scenario with two depths before and after a hydraulic jump of 0.4 m and 1.2 m. Determine the head loss using the related equations discussed.
Recall the specific formulas we've covered relating to energy conservation!
