A1: 50-scale model of a submarine is to be tested in a towing tank under two conditions: motion at the free surface and motion far below the surface. the tests are performed in freshwater. on the surface, the submarine cruises at 24 knots. at what speed should the model be towed to ensure dynamic similarity?
far below the surface, the sub cruises at 0.35 knot. at what speed should the model be towed to ensure dynamic similarity? what must the drag of the model be multiplied by under each condition to give the drag of the full-scale submarine
