A vehicle is towing a tank filled with water and the drag force is measured. The length scale is 1/5 of what of a full-scale prototype would be. The drag force is a function of velocity known as V, length scale is L, fluid properties are p and . T=20C for model and prototype flows. A function would be FD/(PV2L2)=(VL/) i) If the vehicle moves 90km/hr in air, what is the necessary speed to achieve the same dynamic flow? j) What is the estimated drag force on the prototype vehicle, if the model vehicle is 182N?
