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)

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