Formula 8.51
Unsteady evaporation of a liquid
Input(s)
S: Surface Area $\left(\mathrm{cm}^{2}\right)$
$\varnothing$: Location of Film $(\mathrm{cm})$
$D_{A B}$: Difussivity $\left(\mathrm{cm}^{2} / \mathrm{s}\right)$
$\mathrm{t}$: Time $(\mathrm{s})$
Output(s)
$V_{a}$: Rate of Evaporation $(\mathrm{cc} / \mathrm{s})$
Formula(s)
$$ \mathrm{V}_{\mathrm{a}}=\mathrm{S} * \varnothing *\left(\left(\frac{4 * \mathrm{D}_{\mathrm{AB}} * \mathrm{t}}{\pi}\right)^{0.5}\right) $$
