Question 1

What does displacement thickness indicate?

  • The increase in fluid speed.
  • The deflection of streamlines due to boundary layer effects.
  • The total thickness of the fluid layer.

💡 Hint: Link this concept to how boundaries affect fluid flow.

Question 2

True or False: The Reynolds number can help determine the type of flow (laminar or turbulent).

  • True
  • False

💡 Hint: Reflect on critical values indicating flow types.

Challenge Problems

Push your limits with challenges.

Question 1

A flat plate in a wind tunnel has a 1m length and faces airflow at a speed of 5 m/s. Calculate the boundary layer thickness at the trailing edge given the kinematic viscosity of air is 1.5 x 10^-5 m²/s. Show your calculations.

💡 Hint: Use the formula relating Reynolds number and the boundary layer thickness.

Question 2

Determine the implications of a high Reynolds number on drag forces in a fluid flow over a flat plate. How would this affect design considerations in engineering?

💡 Hint: Think about how flow states correlate with design choices.
