Question 1.
Define uniform flow in one sentence.
Show hintHide hint
Think about how fluid properties behave in a straight channel.
Question 2.
What is the no-slip condition?
Show hintHide hint
Consider what happens when fluid touches a wall.
3Question 3.
What defines uniform flow?
- Velocity changes with position
- Velocity remains constant
- Velocity changes with time
Show hintHide hint
Consider how flows behave in straight channels.
4Question 4.
In non-uniform flow, fluid properties:
- True: Change across points
- False: Remain constant across points
Show hintHide hint
Think about how water behaves in a turbulent river.
Question 5.
Given a river with a uniform flow speed of 3 m/s at the center and a no-slip condition near the banks causing variable speeds down to 0 m/s at the edges, calculate the velocity gradient near the edge.
Show hintHide hint
Consider applying the formula for gradient as the change in velocity over distance.
Question 6.
If a flow field has a defined no-slip condition at a boundary, analyze how this affects the characteristics of fluid flow in a channel design aimed at maintaining non-uniformity near solid surfaces.
Show hintHide hint
Think how engineers might design channels to facilitate flow while accounting for the no-slip condition.
