Air is flowing over a smooth plate with a velocity of 8 m/s. The length of the plate is 1.5 m and width is 1 m. Critical Reynolds number is 5 x 105. Find the maximum distance from the leading edge up to which laminar boundary layer exists and find the boundary layer thickness at that point. Also, determine the distance from leading edge of the plate at which laminar boundary layer thickness is 5 mm and find the total drag force up to that point on one side of the plate. Kinematic viscosity of air is 0.15 stokes and density of air is 1.24 kg/m. Polynomial velocity profile shall be considered for the laminar boundary layer
