3 cards from this section. Quick, good the night before a test.
Define a hydraulic jump.
Think about flow changes next to spillways.
What does a Froude number greater than 1 indicate?
Recall the relationship between flow states.
What is the Froude number for a flow with speed 5 m/s and depth 0.3 m?
Calculate using the known formula.
True or False: A hydraulic jump reduces flow energy.
Think about flow conditions right before and after the jump.
In a rectangular channel with a width of 2 m, given a discharge of 4 m³/s and an upstream depth of 0.5 m, calculate the sequent depth and energy loss.
Start with finding the velocity using Q/A.
Derive the relationship for energy loss based on the changes in y1 and y2 in a hydraulic jump.
Recall the use of terms for kinetic and potential energy.
