10 cm 40 cm U = 10 m/s U = 10 m/s 40 cm 10 cm (a) (b) A thin plate of size 40 cm x 10 cm is aligned parallel to a freestream with the orientations (a) and (b) shown above. You can assume laminar boundary layer. The fluid is air at standard conditions with velocity U = 10 m/s. For each orientation, calculate: (a) The momentum thickness and displacement thickness 8* at the trailing edge of the plate. (b) The drag of the plate. (c) Provide a physical explanation for any difference in the drag of the two orientations. 10 cm 40 cm U = 10 m/s U = 10 m/s 40 cm 10 cm (a) (b) A thin plate of size 40 cm x 10 cm is aligned parallel to a freestream with the orientations (a) and (b) shown above.
