Q1: Atmospheric air at 21 °C is flowing parallel to a flat plate at a velocity of 3 m/s. Assuming cubic velocity profile and using exact Blasius solution, estimate the boundary layer thickness and the local coefficient of drag at x-1.2 m from the leading edge of the plate. Also find the deviation of the approximate solution from the exact solution, the kinematic viscosity of air at 21 °C is 1.54x10 m/s². 2
