Show hintHide hint
Look for how motion is described in relation to space.
Question 2.
What are streamlines?
Show hintHide hint
Think about how you might visualize fluid flow.
3Question 3.
Which equation is vital for fluid flow analysis?

Show hintHide hint
Think about how mass is conserved in flow.
4Question 4.
True or false: Streamlines and pathlines are the same in a steady flow.
- True
- False
Show hintHide hint
Consider what steady flow means.
Question 5.
Given a scenario where a fluid is flowing steadily through a pipe that narrows at one end, how would the velocity and pressure change? Develop a model to illustrate your findings.
Show hintHide hint
Consider the relationship between area, velocity, and pressure.
Question 6.
Describe the effects of a temperature gradient and how it would change fluid density in a heated tank.
Show hintHide hint
Reflect on how heat changes molecular motion and spacing.
