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)
\[
\mathrm{V}_{\mathrm{a}}=\mathrm{S} * \varnothing *\left(\left(\frac{4 * \mathrm{D}_{\mathrm{AB}} * \mathrm{t}}{\pi}\right)^{0.5}\right)
\]
