Q4) Define the boundary layer, then find the thickness of boundary layer, shear stress, drag force and coefficient of drag in terms of Re for the velocity profile of laminar boundary layer u/U-4(y/8)-6(y/8)5. Calculate the boundary layer thickness and drag force if the air flows over a sharp edged flat plate 1m long and 0.5m wide at a velocity 0.9m/s, the air density 1.23 kg/m³ and the kinematic viscosity is 1.46*10.5 m/s².
