Friction factor for creeping flow around a sphere

Input(s)

D: Diameter (ft)

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

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

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

Output(s)

f: Friction Factor (dimensionless)

Formula(s)

$$ \mathrm{f}=\frac{24 * \mu}{\mathrm{D} * \mathrm{v} * \rho} $$
