2 cards from this section. Quick, good the night before a test.
What is a hydraulic jump?
Think about what happens when fast water meets slow water.
What does the Froude number indicate?
It’s a way to understand flow velocity compared to wave speed.
What is the condition of flow during a hydraulic jump?
Recall definitions of flow types.
True or False: Energy losses during a hydraulic jump are beneficial.
Consider the effects on energy efficiency.
Given an upstream flow depth of 3 m and velocity of 5 m/s, calculate the downstream flow depth when the flow transitions to a subcritical state. Use conservation equations.
Start by using F = v/sqrt(g*y) to find the initial conditions.
Discuss the design implications of hydraulic jumps in a spillway that experiences high flows. What would engineers need to consider?
Consider both flow conditions and the physical environment.
