Question 1.
What does u represent in fluid dynamics?
Show hintHide hint
Think of flow moving horizontally.
Question 2.
What is w in the context of hydraulic flow?
Show hintHide hint
Consider vertical movement.
3Question 3.
What is the significance of the bottom boundary condition?
- It determines flow characteristics at depth
- It defines surface waves
- It has no effect on pressure
Show hintHide hint
Think about where the water meets the riverbed.
4Question 4.
True or False: A dynamic free surface boundary can support pressure variations.
- True
- False
Show hintHide hint
Reflect on how free surfaces behave in comparison to fixed ones.
Question 5.
Given a variable seabed depth function, h(x), describe how you would determine flow velocities u and w at various depths.
Show hintHide hint
Consider how height variations affect flow velocity.
Question 6.
If waves create distortions on the free surface, how would you apply both dynamic and kinematic conditions to predict stability in structural designs?
Show hintHide hint
Think back to how we discussed pressure at dynamic surfaces.
