Question 1.
Define streamlines in your own words.
Show hintHide hint
Think about how streamlines reflect velocity.
Question 2.
What does a pathline represent?
Show hintHide hint
Consider particles' movement in a flow.
3Question 3.
What is a streamline in fluid dynamics?
- A line representing particle history
- A line tangent to the velocity vector
- The path of a fluid particle over time
Show hintHide hint
Think of direction and tangents.
4Question 4.
True or False: In unsteady flow, streamlines and pathlines are the same.
- True
- False
Show hintHide hint
Consider how flow characteristics change over time.
Question 5.
Given a steady flow in a pipe, trace a fluid particle's path and discuss the relationship between its pathline and the streamlines observed.
Show hintHide hint
Consider how steady flow characteristics minimize changes.
Question 6.
If a dye is released in a turbulent flow, describe how the resulting streakline would differ from pathlines in a steady flow scenario.
Show hintHide hint
Reflect on the unpredictable nature of turbulent flow compared to steady conditions.
