2.1. Dynamic and Static Pressure Components

Try these first

1. 1.

   What is dynamic pressure?

   Hint

   Refer to pressure influenced by velocity changes.

2. 2.

   Define static pressure.

   Hint

   Think about the weight of water above a point.

3. 3.

   What defines dynamic pressure?

   • Pressure at rest
   • Pressure due to fluid depth
   • Pressure related to fluid motion

   Hint

   Think about wave actions.

4. 4.

   The group celerity is higher than the individual wave speed. True or False?

   • True
   • False

   Hint

   Consider how waves combine.

5. 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.

   Hint

   Use the dynamic pressure formula.

6. 6.

   If the wave height of a progressive wave is 2 meters, what is the potential energy at depth corresponding to this wave height?

   Hint

   Remember the formula for potential energy due to waves.
