Consider a smooth sphere, of diameter d, immersed in a fluid moving with speed v. the drag force on a 15-ft diameter weather balloon in air moving at 6 ft/s is to be calculated from test data. the test is to be performed in water using a 3-in. diameter model. under dynamically similar conditions, the model drag force is measured as 0.94 lbf. evaluate (a) the model test speed. (b) the drag force expected on the full-scale balloon.
