Question 1
What occurs in the transition zone of a boundary layer?
- Flow remains laminar
- Flow transitions to turbulent
- Flow is in equilibrium
💡 Hint: Remember the effects of Reynolds number.
Question 2
True or False: The laminar sub-layer is thicker than the turbulent boundary layer.
- True
- False
💡 Hint: Think about the characteristics of these layers.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a flow situation where the Reynolds number is very low. What characteristics would you expect in the boundary layer, and how does this impact shear stress calculations?
💡 Hint: Focus on how the flow regime influences calculations.
Question 2
Analyze a scenario where the boundary layer thickness is measured at a different percentage of free stream velocity. How would this affect your calculations regarding displacement and momentum thickness?
💡 Hint: Consider how changing reference points impacts analysis.
