Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the definition of displacement thickness?
- A measure of effective flow area reduction
- The extent to which momentum is lost
- The thickness of the liquid at the surface
- None of the above
💡 Hint: Think about how displacement thickness affects the entire flow region.
Question 2
True or False: Momentum thickness can be computed from velocity profiles.
- True
- False
💡 Hint: Link this to how flows behave along surfaces.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the displacement thickness for a given laminar flow situation with known velocity distributions. If u = 0.6U at y = 0.005m, and U is the free stream velocity, what would B4* be?
💡 Hint: Focus on integrating within the range defined by your boundaries.
Question 2
Given velocity profiles for a turbulent flow, derive the momentum thickness and discuss its implications on drag force design.
💡 Hint: Incorporate experimental or empirical data for accuracy.
