Question 1.
What is the formula for wave speed in open channels?
Show hintHide hint
Think about how wave speed relates to gravity and fluid depth.
Question 2.
Define subcritical flow.
Show hintHide hint
Consider the relationship between water velocity and wave speed.
3Question 3.
What is the speed of waves in a shallow channel if the depth is 3 m?
- 1.5 m/s
- 4.3 m/s
- 5.4 m/s
Show hintHide hint
Consider the formula for wave speed that relates depth and gravity.
4Question 4.
True or False: The greater the fluid density, the faster the wave speed.
- True
- False
Show hintHide hint
Remember the derivation involving density cancellation.
Question 5.
Calculate the wave speed in a channel with varying depths of 0.5 m and 3 m under standard gravity. Then analyze how this affects the wave propagation.
Show hintHide hint
Use the relationship c = √(gy) for solutions.
Question 6.
Consider a channel where the depth suddenly changes from 2 m to 5 m. If the initial wave speed was 3 m/s, calculate the new wave speed and discuss its implications.
Show hintHide hint
Reapply the wave speed formula to assess the impact of changing depths.
