Flashcard drill
2 cards from this lesson. Good the night before a test.
Try these first
- 1.
Define laminar flow.
Hint
Think about the fluid behavior at low speeds.
- 2.
What is displacement thickness?
Hint
It relates to how the flow changes around an object.
- 3.
What characterizes laminar flow?
- Smooth and orderly flow
- Chaotic flow
- High Reynolds number
Hint
Recall the flow patterns at low speeds.
- 4.
True or False: Displacement thickness accounts for the volume of fluid displaced due to a flat plate.
- True
- False
Hint
Think about how streamlines behave near boundaries.
- 5.
Calculate the boundary layer thickness for a flat plate in a wind tunnel with a uniform speed of 4 m/s assuming kinematic viscosity is 1.5 × 10^-5 m²/s.
Hint
Evaluate Reynolds number first.
- 6.
Given a momentum thickness of 0.002m, how much momentum deficit does this indicate for the flow?
Hint
Consider averaging the velocity profile.
