Diffusion in a moving film
Input(s)
H: Initial Height of Gas Column (cm)
C: Concentration \((\mathrm{g} / \mathrm{cc})\)
\(\mathrm{t}\): Time \((\mathrm{s})\)
Output(s)
\(\mathrm{h}(\mathrm{t})\): Height of Gas Interface \((\mathrm{cm})\)
Formula(s)
\[
\mathrm{h}(\mathrm{t})=\mathrm{H} *\left(\left(1+\left(\frac{\mathrm{Ct}}{\mathrm{H}^{2}}\right)^{0.5}\right)-1\right)
\]
