Consider a flat plate, that is 4m wide and 1m long. The plate is immersed water flowing at 0.2m/s (free stream parallel to the plate). Density of the water is 1000 kg/mº Kinematic viscosity of the water is 1.57x10mºsAssume the velocity profile is quadratic and a laminar boundary layer is formed. a. Find the displacement thickness at the center of the plate b. Find the shear stress at the center of the plate
