The drag of a small submarine hull is desired when it is moving far below the free surface of water. A scale model is to be tested. What dimensionless 10 group should be duplicated between the model and prototype and why? If the drag of the prototype at 1 knot is desired, at what speed should model be moved to give the drag to be expected by the prototype? Would his result still be true if the prototype were to be moved close to the surface? Support your response with a model law and state any two example ?
