Question 1

What defines a boundary layer?

  • Region of uniform velocity
  • Region with velocity changing from zero to free stream
  • Layer of fluid with no viscosity

💡 Hint: Think about how fluids behave near surfaces.

Question 2

True or False: A high Reynolds number indicates laminar flow.

  • True
  • False

💡 Hint: Recall the defining characteristics of flow states.

Challenge Problems

Push your limits with challenges.

Question 1

The velocity profile of a fluid flow over a flat plate is observed at several points with a Reynolds number of 50,000. Calculate and discuss the boundary layer thickness and the expected shear stress.

💡 Hint: Remember the formulas connecting boundary layer thickness and Reynolds numbers.

Question 2

Design a small experimental setup to measure how boundary layer thickness varies with different Reynolds numbers. Discuss the challenges faced during your experiment.

💡 Hint: Consider the tools you would need for effective fluid flow measurement.
