The drag force on a boat hull, Fp, is known to be a function of the hull length, L, its velocity, V, the properties of the fluid in which it is floating (density, P), and the acceleration due to gravity, g. V 1 60 - (a) For Fp = f( Vg, L, p), and using V, L, p as repeating variables, determine the non-dimensional parameters for this problem. р
(b) Tests are to be done in a water tank with a 1:12 scale model. At what velocity should the model be towed to simulate a full-scale speed of 10 m/s?
(c) If the model drag is found to be 400 N, what is the full-scale drag?
