A. Use dimensional analysis to determine how the drag force F depends on the speed V. 7.12 At very low speeds, the drag on an object is independent of fluid density. Thus the drag force, F, on a small sphere is a function only of speed, V, fluid viscosity,, and sphere diameter, D. Use dimensional analysis to determine how the
