What is the main factor determining the flow type in boundary layer theory?
💡 Hint: Recall how the flow behaves under different Reynolds numbers.
True or False: A negative du/dy value at the wall indicates that flow has separated.

Challenge Problems
Push your limits with advanced challenges
A fluid with a viscosity of 0.001 Ns/m² flows over a flat plate of 2m length. If the velocity at the edge of the boundary layer is 0.2 m/s, calculate the boundary layer thickness at this point, and discuss how changing viscosity would affect separation.
💡 Hint: Calculate Re before using thickness formula.
You have two flow profiles: one with higher velocities and high adverse pressure gradients; the other with lower velocities and favorable gradients. Explain how each affects boundary layer separation.
💡 Hint: Focus on pressure gradient effects on flow behavior.
