Challenge Problems
Push your limits with advanced challenges
Given a flat plate of length 1m in air flowing at a free stream velocity of 25 m/s, calculate the boundary layer thickness if it is laminar. Assume the kinematic viscosity of air as 1.5 x 10^-5 m²/s.
💡 Hint: Start by calculating the Reynolds number first.
In a wind tunnel experiment, a flat plate has a boundary layer formed at its leading edge. Can you derive the shear stress acting on the plate if the velocity gradient at the wall is 2 s^-1 and the dynamic viscosity is 0.001 Pa.s?
💡 Hint: Use the shear stress equation from fluid dynamics.
