Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does displacement thickness represent?

  • The thickness of fluid at the wall
  • The distance a streamline is pushed away from the wall
  • The total mass of fluid flowing

💡 Hint: Think about how streamline behavior changes due to viscosity.

Question 2

True or False: Momentum thickness relates to the loss of mass flux in fluid flow.

  • True
  • False

💡 Hint: Refer to the definitions of momentum and mass flux before answering.

Challenge Problems

Push your limits with challenges.

Question 1

If the boundary layer thickness is given as delta = 0.1 m in a water system, and the velocity profile is u/U = 0.5y/delta, calculate the displacement and momentum thickness.

💡 Hint: Remember to apply the integral limits correctly to derive each thickness.

Question 2

A flat plate experiences a flow with a velocity profile of u/U = y^2/delta^2. Find the energy thickness and discuss its relevance in fluid systems.

💡 Hint: Approach the problem analytically while understanding how energy plays a role in fluid flow.
