A thin, flat plate of 0.6 m square is immersed in a parallel stream of air at atmospheric pressure and 15 ºC flowing at a velocity of 6 m/s. Neglect edge effects. a) Determine the drag force exerted on the plate. b) Determine the boundary layer thickness and the local drag coefficient at a distance 0.3 m from the leading edge.
Question 1 Drag tests show that the drag of a circular disc placed normally to the free-stream velocity (see Figure 1) is a function of the fluid velocity, Vo, the fluid density, p, the fluid viscosity, ?, the disc diameter, D, the free-stream turbulence root mean square velocity, ums, and the turbulence length scale Lx. Here urms and L. are in m/s and m, respectively. By using the Step-by-step method dimensional analysis, develop the r- groups that could be used...
