Challenge Problems
Push your limits with challenges.
Question 1
Calculate the boundary layer thickness for a flat plate in a wind tunnel with a uniform speed of 4 m/s assuming kinematic viscosity is 1.5 × 10^-5 m²/s.
💡 Hint: Evaluate Reynolds number first.
Question 2
Given a momentum thickness of 0.002m, how much momentum deficit does this indicate for the flow?
💡 Hint: Consider averaging the velocity profile.
