Question 1
What defines the transition zone from laminar to turbulent flow?
- Increase in temperature
- Decrease in velocity
- Increase in Reynolds number
💡 Hint: Consider how fluid characteristics change downstream.
Question 2
True or False: The laminar sub-layer completely eliminates the effects of turbulence above it.
- True
- False
💡 Hint: Think about how layers interact rather than eliminate each other.

Challenge Problems
Push your limits with challenges.
Question 1
A plate has a boundary layer with a thickness of 0.02m. Calculate the percentage velocity deficit at a point where the flow is 70% of the free stream velocity.
💡 Hint: Understand the concept of velocity profiles and how they interact with boundary layers.
Question 2
Using the definitions of momentum thickness and energy thickness, derive expressions comparing their values using the same flow conditions.
💡 Hint: Think critically about conservation principles in fluid flow.
