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