Diffusion Into a falling liquid film (gas absorption)
Input(s)
c: Concetration \(\left(\mathrm{mol} / \mathrm{cm}^{3}\right)\)
\(D_{A B}\): Diffusivity \(\left(\mathrm{cm}^{2} / \mathrm{s}\right)\)
\(v_{\max }\): Velocity of Dropping Particle \((\mathrm{cm} / \mathrm{s})\)
z: Height of Column \((\mathrm{cm})\)
Output(s)
\(\mathrm{N}\): Molar Flux \(\left(\mathrm{mol} / \mathrm{cm}^{2} \mathrm{~s}\right)\)
Formula(s)
\[
\mathrm{N}=\mathrm{c} *\left(\frac{\mathrm{D}_{\mathrm{AB}} * \mathrm{v}_{\max }}{\pi * \mathrm{z}}\right)^{0.5}
\]
