3 cards from this section. Quick, good the night before a test.
Define hydraulic jump in your own words.
Think about the flow conditions before and after.
What does a Froude number greater than 1 indicate?
Recall the definition of supercritical flow.
What critical condition does a Froude number greater than 1 represent?
Recall the definitions for flow states.
True or False: Energy loss in hydraulic jumps is zero.
Consider the nature of hydraulic jumps.
Design a channel where a hydraulic jump reduces flow velocity from 10 m/s to 2 m/s with an initial depth of 0.5 m. Calculate the necessary elements.
Start with Fr1 and determine the downstream conditions.
During a hydraulic jump, the initial velocity is 12 m/s, and the suppercritical state causes energy loss of 5 m. Determine the sequent depths and changes.
Remember to keep track of velocity after the jump.
