Question 1
What defines a boundary layer?
- It occurs in the bulk of the flow.
- It is in the region of flow near a surface.
- It is a region of turbulent flow only.
💡 Hint: Think about where the viscous effects are significant.
Question 2
Reynolds number helps determine whether the flow is laminar or turbulent.
- True
- False
💡 Hint: Recall what the critical values indicate.
