Question 1.
What is dynamic pressure?
Show hintHide hint
Refer to pressure influenced by velocity changes.
Question 2.
Define static pressure.
Show hintHide hint
Think about the weight of water above a point.
3Question 3.
What defines dynamic pressure?
- Pressure at rest
- Pressure due to fluid depth
- Pressure related to fluid motion
Show hintHide hint
Think about wave actions.
4Question 4.
The group celerity is higher than the individual wave speed. True or False?
- True
- False
Show hintHide hint
Consider how waves combine.
Question 5.
Calculate the dynamic pressure if the wave's velocity potential changes at a rate of 5 m/s with a fluid density of 1000 kg/m³.
Show hintHide hint
Use the dynamic pressure formula.
Question 6.
If the wave height of a progressive wave is 2 meters, what is the potential energy at depth corresponding to this wave height?
Show hintHide hint
Remember the formula for potential energy due to waves.
