Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is displacement thickness?
- The thickness of fluid in the boundary layer
- The distance a streamline is displaced
- The volume of fluid lost
💡 Hint: Consider what happens to a streamline due to viscous effects.
Question 2
True or False: Momentum Thickness is the same as Displacement Thickness.
- True
- False
💡 Hint: Recall the definitions of both concepts.

Challenge Problems
Push your limits with challenges.
Question 1
For a flat plate, given the velocity profile u/U = y^3/delta^3, derive the displacement thickness, momentum thickness, and energy thickness.
💡 Hint: Use integrals for each to find thickness values using given velocity profiles.
Question 2
Discuss the effects of a turbulent boundary layer on the three thicknesses compared to a laminar boundary layer.
💡 Hint: Contrast between flow nature in laminar versus turbulent conditions.
