Question 1.
Define deep water and the condition that characterizes it.
Show hintHide hint
Think about how depth relates to wavelength.
Question 2.
What does velocity potential represent?
Show hintHide hint
Consider what parameters are related to velocity.
3Question 3.
What defines deep water?
- d/L > 0.05
- d/L < 0.05
- d/L = 0.05
Show hintHide hint
Consider the definitions we discussed.
4Question 4.
In shallow water, wave speed only depends on what?
- Water pressure
- Wave height
- Water depth
Show hintHide hint
Recall the equation we learned for shallow waves.
Question 5.
Given a wave with a wavelength of 50m and a depth of 1m, identify whether it is in deep, intermediate, or shallow water, and calculate the speed if it's shallow.
Show hintHide hint
Analyze the depth-to-wavelength ratio first.
Question 6.
In intermediate waters, if d = 5m and L = 100m, compute the celerity and discuss dependency on water depth.
Show hintHide hint
Remember to justify why you use deep-water equations despite being intermediate.
