MCQ (More than One Correct Answer)

-0

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.

$\frac{F_D}{\rho V^2 D^2}$

$\frac{\rho F_D}{V^2 D^2}$

$\frac{\rho V D}{\mu}$

$\frac{\mu \rho}{V D}$
