The drag force, $F_{D}$ on a sphere due to a fluid flowing past the sphere is a function of viscosity, $\mu$, the mass density, $\rho$, the velocity of flow, $V$, and the diameter of the sphere, $D$.
Pick the relevant (one or more) non-dimensional parameter(s) pertaining to the above process from the following list.
- $\frac{F_{D}}{\rho V^{2} D^{2}}$
- $\frac{\rho F_{D}}{V^{2} D^{2}}$
- $\frac{\rho V D}{\mu}$
- $\frac{\mu \rho}{V D}$
