A thin flat plate 3 ft long and 2 ft wide is towed fully submerged at 10 fts in a towing basin containing water with p 2 slugsft

A thin flat plate 3 ft long and 2 ft wide is towed fully submerged at 10 ft/s in a towing basin containing water with p = 2 slugs/ft’, p = 2 x 10h5 lb-s/ft*. The drag force is observed to be 3 lb. If the experiment were now to be run in a wind tunnel with an air stream velocity of 50 ft/s, p = 0.0024 slug/f?, p = 3.8 x 10e5 lb-s/ft*, what should be the dimensions of the plate for dynamic similarity? What should be the drag force on this plate with dimensions as given? Is it possible to obtain complete dimensional similarity in this case? Comment on the feasibility of this model.
