Air moves over a 10 m long flat plate. The transition from laminar to turbulent flow takes place between Reynolds numbers of 2.5 × 106 and 3.6 × 106. The free stream velocity is 30 m/s and v = 1.5 x 10-5 m²/s. What is the maximum distance from the front edge of the plate along which one expects laminar flow in the boundary layer?
