Document Summary
A viscous fluid flows past a flat plate such that the boundary layer thickness at a distance 1. 3 m from the leading edge is 12 mm. Determine the laminar boundary layer thickness at a distance of 0. 2, 2 and 20 mm from the leading edge. A laminar boundary layer velocity profile is approximated by the following expression: 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, estimate the location on the wing (i. e. , the distance x from the leading edge) where the flow transitions to turbulent flow. Assume that the critical reynolds number at which the flow transitions from laminar to turbulent flow is given as rexcr=5x105. A 38. 1 table tennis ball of diameter 38. 1 mm and weight of 0. 0245 n is released from the bottom of a swimming pool (filled with water).
