Friction factor in packed column (laminar)

Input(s)

в: Fractional Void Space (dimensionless)

DPD_{P}: Diameter of Particles (ft)

v0\boldsymbol{v}_{\mathbf{0}}: Velocity of Fluid (ft/s)(\mathrm{ft} / \mathrm{s})

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

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

Output(s)

f: Friction Factor (dimensionless)

Formula(s)

f=((1ε)2ε3)(75μρDPvo)\mathrm{f}=\left(\frac{(1-\varepsilon)^{2}}{\varepsilon^{3}}\right) *\left(\frac{75 * \mu}{\rho * D_{\mathrm{P}} * \mathrm{v}_{\mathrm{o}}}\right)
