Consider the journey of a single leaf floating in water.
3Question 3.
What does a streamline represent?
- Pressure variation
- Fluid direction
- Density change
Show hintHide hint

4Question 4.
True or False: Pathlines and streamlines are the same.
- True
- False
Show hintHide hint
Think about their definitions!
Question 5.
Assume a fluid flows through a Hele-Shaw setup, and you observe varying dye patterns. How can this inform about the flow regime?
Show hintHide hint
Consider how the pattern's regularity or irregularity signifies different flow characteristics.
Question 6.
In a CFD simulation of fluid around a triangular object, what factors might affect the accuracy of the results?
Show hintHide hint
Think about how each of these elements relates to simulations of actual fluid dynamics.
