Show hintHide hint
Recall why distinguishing these flows is important.
3Question 3.
What is the relationship between wave speed and fluid depth?
- Directly proportional
- Inversely proportional
- No relationship
Show hintHide hint
Think about the derived equation and how changing depth affects speed.
4Question 4.
True or False: The wave speed is affected by wave amplitude for small amplitude waves.
- True
- False
Show hintHide hint
Refer back to the wave speed equation and its derivation.
Question 5.
Given a wave speed of 5 m/s in a channel depth of 2m, calculate the effective Froude number when fluid flows at 3 m/s.
Show hintHide hint
Consider the relationship between wave speed and flow.
Question 6.
A rectangular channel has a depth of 3 meters. If the fluid at the surface moves at 6 m/s, calculate the wave speed and assess the flow condition.
Show hintHide hint
Compare fluid speed to wave speed to determine the flow condition.
