Question 1
What is the boundary layer thickness (δ)?
- The distance where velocity is zero
- The distance where velocity is 50% of free stream
- The distance where velocity is 99% of free stream
💡 Hint: Think about how the flow is defined near the surface.
Question 2
True or False: Turbulent boundary layers have smooth and layered flow.
- True
- False
💡 Hint: Consider how turbulence impacts flow structure.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a scenario where an airplane wing design needs optimization. How would you go about analyzing the boundary layer effects on drag and lift? Discuss the steps involved.
💡 Hint: Think about the factors influencing airflow over surfaces.
Question 2
A flat plate has a boundary layer thickness of 1 cm at a certain flow speed. If the flow speed is doubled, how would you expect the boundary layer thickness to change? Justify your reasoning.
💡 Hint: Consider the relationship between inertia and viscosity in fluid dynamics.
