Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the primary function of the boundary layer?
- To increase drag
- To allow for the development of turbulence
- To reduce the velocity of the flow near a surface
- To create laminar flow conditions
💡 Hint: Think of how fluids behave near surfaces.
Question 2
True or False: Displacement thickness accounts for the outer streamline shift due to the boundary layer effect.
- True
- False
💡 Hint: Consider what happens to streamlines near a wall.
