Friction factor in packed column (laminar)

Input(s)

в: Fractional Void Space (dimensionless)

$D_{P}$: Diameter of Particles (ft)

$\boldsymbol{v}_{\mathbf{0}}$: 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)

$$ \mathrm{f}=\left(\frac{(1-\varepsilon)^{2}}{\varepsilon^{3}}\right) *\left(\frac{75 * \mu}{\rho * D_{\mathrm{P}} * \mathrm{v}_{\mathrm{o}}}\right) $$
