Air flowing past an object typically exerts a drag force on the object. For the given shape of the object, the drag force is commonly assumed to depend on the speed at which the air approaches the object, the size of the object, and the density and viscosity of the air. At sufficiently high velocities, the drag force asymptotically becomes independent of the viscosity of the fluid. Use dimensional analysis to express the asymptotic functional behavior of the drag force and state the functional relationship between the drag force and the influencing variables under the asymptotic condition.
