A spherical balloon that is to be used in air at 60°F and atmospheric presssure is tested by towing a 1/4scale model in a lake. The model is 1 ft in diameter, and a drag of 15 lbf is measured when the model isbeing towed in deep water at 5 ft/s. What drag (in pounds force and newtons) can be expected for theprototype in air under dynamically similar conditions? Assume that the water temperature is 60°F.
