Question 1.
What is the definition of velocity potential?
Show hintHide hint
Think about how we represent fluid movement.
Question 2.
Name one assumption made in deriving velocity potential.
Show hintHide hint
Consider the properties of fluids we typically ignore.
3Question 3.
What is the Laplace equation used for in hydraulic engineering?
- To calculate pressure
- To describe velocity potential
- To measure fluid density
Show hintHide hint
It's a fundamental equation in classifying flow types.
4Question 4.
True or False: At the seabed, the vertical velocity component is zero.
- True
- False
Show hintHide hint
Think about the nature of fixed boundaries.
Question 5.
Using the concepts discussed, calculate how wave motion changes if the seabed is no longer horizontal but has a slope determined by a function h(x). Provide the equation governing the new wave motion.
Show hintHide hint
Apply the same principles but consider gradients introduced by the sloping seabed.
Question 6.
Discuss the effects of assuming that pressure at the free surface is not uniform. What complications might arise in the dynamic boundary conditions?
Show hintHide hint
Consider how stability and consistency in water surface pressure impacts flow.
