Question 1.
What is the formula for calculating wave speed in an open channel?
Show hintHide hint
Think about the relationship between wave properties and water depth.
Question 2.
What does a Froude number less than 1 indicate?
Show hintHide hint
Consider the flow behavior in relation to wave speed.
3Question 3.
What is the speed of a wave in an open channel at a depth of 1 meter?
- 3.13 m/s
- 4.43 m/s
- 2.12 m/s
Show hintHide hint
Recall the wave speed formula and substitute y = 1.
4Question 4.
True or False: Fluid density significantly influences the speed of solitary waves.
- True
- False
Show hintHide hint
Consider the balance of forces and the equation derived.
Question 5.
A pond of depth 5 meters experiences waves with a speed of 7 m/s. Calculate the acceleration due to gravity on this planet.
Show hintHide hint
Rearrange the wave-speed formula to solve for g.
Question 6.
A river with a depth of 1.5 meters and a wave speed of 3.5 m/s is flowing. Is this flow subcritical or supercritical? What Froude number can you compute?
Show hintHide hint
Compare calculated flow speed with wave speed.
