Question 1
What is the relationship between displacement thickness and momentum thickness?
- Both measure the same effect
- They measure different aspects of flow
- Only one affects drag
💡 Hint: Consider their definitions carefully.
Question 2
True or False: Momentum thickness is a direct measure of drag force.
- True
- False
💡 Hint: Think about the concepts being separate yet related.

Challenge Problems
Push your limits with challenges.
Question 1
A flat plate in a fluid flow is experiencing boundary layer formation. Given initial velocity profiles, compute both momentum thickness and displacement thickness at several points along the plate.
💡 Hint: You may need to derive the equations based on given profiles.
Question 2
Analyze how changes in fluid viscosity can impact the momentum thickness behavior on different surfaces—smooth vs. rough.
💡 Hint: Think about how viscous fluids flow differently compared to non-viscous ones.
