Air at free-stream velocity of 8 m/s flows over a thin flat plate of length 5 m and width 1 m. A lamirar boundary layer develops from the leading edge of the flat plate. At Re,= 800 000, the boundary layer becomes a turbulent boundary layer where x is the distance from the leading edge. par = 1.2 kg/m', lais = 1.8 x 10 kg/m.s a) Estimate the length of the laminar boundary layer. b) Estimate the drag force duz the laminar boundary layer on one side of the flat plate. c) Wall shear stress atr=5 m.
