An airplane flies at a speed of 400 mph at an altitude of 10,000 ft. if the boundary layers on the wing surfaces behave as those on a flat plate, (a) estimate the extent of laminar boundary layer flow along the wing. assume a transitional reynolds number of rexcr = 5 x 105. if the airplane maintains its 400 -mph speed but descends to sea-level elevation, (b) estimate the extent of the laminar boundary layer flow. (c) will the portion of the wing covered by a laminar boundary layer increase or decrease compared with its value at 10,000 ft?
