A 1:50 scale model of a ship is to be tested to determine the wave drag. The geometry and surface properties of the ship are such that viscous drag is negligible. In the model test, the model is moved at a velocity of 2 m/s and the measure drag on the model is 20 N. Water at the same temperature is used in both the model and the prototype. What are the corresponding velocity and drag force in the prototype?
