Determination of the diameter of a falling sphere

Input(s)

Re: Reynolds Number (dimensionless)

v: Velocity of Fluid $(\mathrm{ft} / \mathrm{s})$

$\rho$: Density of Fluid $(\mathrm{g} / \mathrm{cc})$

$\mu$: Viscocity of Fluid $(\mathrm{cP})$

Output(s)

D: Diameter $(\mathrm{ft})$

Formula(s)

$$ \mathrm{D}=\frac{\operatorname{Re} * \mu}{\rho * \mathrm{v}} $$
