The drag on a 2-m-diameter satellite dish due to an 64-km/hr wind is to be determined through a wind tunnel test using a geometrically similar 0.4-m-diameter model dish. Assume standard air for both model and prototype. (a) At what air speed should the model test be run? (b) With all similarity conditions satisfied, the measured drag on the model was determined to be 187 N. What is the predicted drag on the prototype dish?
