Question 1.
What is the definition of three-dimensional flow?
Show hintHide hint
Think about the axes in space.
Question 2.
In two-dimensional flow, which velocity component can be neglected?
Show hintHide hint
Consider the minor component.
3Question 3.
Which method follows the fluid particles?
- Eulerian
- Lagrangian
- Neither
Show hintHide hint
Think about how motion is observed.
4Question 4.
True or False: One-dimensional flow has significant velocity in all three dimensions.
- True
- False
Show hintHide hint
Evaluate the number of dimensions involved.
Question 5.
A fluid flows in a rectangular channel that is much wider than it is deep. How would you classify the flow dimensions, and what assumptions can be made?
Show hintHide hint
Evaluate the dimensions of the channel.
Question 6.
You have a scenario with varying depths in a river, but the width is constant. Discuss how you would approach the analysis and flow categorization.
Show hintHide hint
Consider how changes in depth affect the overall flow.
