3) Air flows over a sharp edged flat plate with L=1m,

3) Air flows over a sharp edged flat plate with L=1m, a width of 3m and U=2m/s. For one side of the plate, find the drag force exerted by the fluid on the plate. (25 easy points) The local drag coefficient can be related to the shear stress at the wall Cfx=21U2W(x) and is given as Cfx=Rex0.664 (you get this by solving the NS boundary layer equations or by using vonKarman) Air: =1.23kg/m3;v=/=1.46105m2/s v=xvx+yvy+zvz
