Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does the displacement thickness represent?
- Distance fluid is displaced away from the wall
- Loss of kinetic energy
- Increase in flow velocity
💡 Hint: Think about how flowing near surfaces alters the flow structure.
Question 2
True or False: The momentum thickness considers increases in the kinetic energy of fluid.
- True
- False
💡 Hint: Recall the function of momentum versus kinetic energy.

Challenge Problems
Push your limits with challenges.
Question 1
Given a velocity profile of u/U = 4y/delta, calculate both the displacement thickness and momentum thickness over a flat plate.
💡 Hint: Pay attention to how the velocity profile affects integrals.
Question 2
How would an increase in viscosity affect the displacement thickness in boundary layer flow?
💡 Hint: Think about the effects of increased internal friction on flow behavior.
