Show hintHide hint
Think about scalar functions and fluid equations.
Question 2.
What happens to water particle displacement in shallow water?
Show hintHide hint
Consider how depth influences the shape of the orbit.
3Question 3.
What does the velocity potential describe?
- Flow velocity in a fluid
- Pressure of a fluid
- Density of a fluid
Show hintHide hint
Think about what controls the motion in fluids.
4Question 4.
True or False: In shallow water, particle paths are circular.
- True
- False
Show hintHide hint
Consider how depth changes affect shapes.
Question 5.
Given a specific wave height and wavelength, derive the equations for D and B in both shallow and deep water conditions and discuss how these parameters reflect wave behavior.
Show hintHide hint
Analyze how depth affects these relationships.
Question 6.
Using computational tools, demonstrate the calculation of kd through the equation kd² = y² + y/(1 + Σ from n=1 to n=6 of dn * Y_n. Explain how this aids in practical scenarios.
