5 cards from this section. Quick, good the night before a test.
What is a hydraulic jump?
Think about how depth changes in a river suddenly.
What does the Froude number indicate?
It's a ratio of inertial to gravitational forces.
What is the primary characteristic of a hydraulic jump?
Think about the abrupt shifts in rivers.
The Froude number must be greater than 1 to achieve a hydraulic jump.
Recall what defines supercritical flow.
Calculate the Froude number for a given flow of depth 4m with velocity 10m/s. Discuss whether a hydraulic jump could occur.
Use the relationship of flow depth and velocity to determine Fr.
In a channel, the depth changes from 3m to 1m due to the hydraulic jump. What happens to the energy of the flow?
Consider how potential energy converts to kinetic during a jump.
