Question 1.
What is a hydraulic jump?
Show hintHide hint
Think about sudden changes in a channel.
Question 2.
What does the Froude number indicate?
Show hintHide hint
Consider how flow rates relate to gravity.
3Question 3.
What is the Froude number used for?
- To measure energy loss
- To characterize flow regimes
- To calculate depth
Show hintHide hint
It’s a dimensionless number that relates forces.
4Question 4.
True or False: Hydraulic jumps can occur in subcritical flow.
- True
- False
Show hintHide hint
Recall the definitions of flow types.
Question 5.
A rectangular channel experiences a hydraulic jump. If the upstream Froude number is 3, calculate the ratio y2/y1.
Show hintHide hint
Start with the Froude number's relationship to depths.
Question 6.
Analyze the head loss when flow transitions from a sluice gate with a Froude number of 1.5. Calculate the energy loss if y1 = 2m.
