6.4. Visualization of Flow

Try these first

1. 1.

   What is a streamline?

   Hint

   Think about how velocity is represented in a flow.

2. 2.

   What do we call the path traced by a fluid particle over time?

   Hint

   Remember the term describes the movement over time.

3. 3.

   What describes a streamline?

   • A fixed line in the fluid
   • A line tangent to the velocity vector
   • A line that intersects with fluid particles

   Hint

   Think about how streamlines represent motion.

4. 4.

   True or False: In steady flow, pathlines and streaklines may differ.

   • True
   • False

   Hint

   Recall the characteristics of steady flow.

5. 5.

   Design an experiment to visualize the flow around an object in a fluid. Detail how you would set up the experiment and what results you would expect to see.

   Hint

   Consider the properties of fluid motion and experimental setups for visualization.

6. 6.

   Using your knowledge of streamlines and pathlines, explain how you would determine flow direction around a complex structure.

   Hint

   Reflect on how flow characteristics change near obstacles.
