Question 1

What defines the boundary layer thickness?

  • The distance to where velocity is 75% of free stream
  • The distance where velocity is 99% of free stream
  • The thickness of the entire laminar sublayer

💡 Hint: Remember how we measure boundary layer effects.

Question 2

True or False: The laminar sublayer exists only in turbulent flow.

  • True
  • False

💡 Hint: Consider the flow types.

Challenge Problems

Push your limits with challenges.

Question 1

Given a fluid with a viscosity of 1 mPa.s and a density of 1000 kg/m³ flowing over a flat plate with a length of 5 m, what is the boundary layer thickness at the trailing edge if the free stream velocity is 2 m/s?

💡 Hint: Apply the appropriate formulas for boundary layer thickness using the free stream conditions.

Question 2

Discuss the implications of increased boundary layer thickness on the drag force acting on an object moving through a fluid.

💡 Hint: Consider how this might affect performance in engineering designs.
