Challenge Problems
Push your limits with advanced challenges
A fluid flows past a flat plate with a length of 5m. If the free stream velocity is 10 m/s and the kinematic viscosity of the fluid is 0.001 m2/s, calculate the boundary layer thickness at the end of the plate.
💡 Hint: Remember to compute Reynolds number first!
Describe how the transition from laminar to turbulent flow can be experimentally determined, using examples from wind tunnel studies.
💡 Hint: Consider what techniques are often used in fluid dynamics experiments.
