Interactive Quizzes

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

Question 1

What is the primary phenomenon described by the boundary layer theory?

  • A. Fluid remains stationary at the surface.
  • B. Fluid velocity is maximum at the boundary.
  • C. Fluid velocity changes from zero at the wall to free-stream velocity.
  • D. Fluid accelerates continuously without changes.

💡 Hint: Focus on how fluid interacts with surfaces.

Question 2

True or False: The Reynolds number helps predict whether flow is laminar or turbulent.

  • True
  • False

💡 Hint: Recall its critical thresholds that affect layering.

Challenge Problems

Push your limits with challenges.

Question 1

A river flows at 3 m/s over a flat plate with planar dimensions 3 meters long. If the kinematic viscosity of the water is 0.001 m²/s, determine the Reynolds number after 2 meters from the leading edge.

💡 Hint: Apply the Reynolds number formula to find the solution.

Question 2

Discuss the impact of increasing boundary layer thickness on flow separation during high-velocity conditions.

💡 Hint: Consider the broader implications in design and aerodynamics.
