Problem

Chlorine gas $($density $=1\mathrm{.}165k\frac{g}{m^3})$ is stored

at $30C$ in a permeable cylindrical container

which has an outer diameter of $0\mathrm{.}25m,$ a wall

thickness $5mm$ and length of $2m.$ The

cylinder is exposed to ambient air.

If the container is charged to an initial

pressure of $5$bar $,$ at what would be the mass

diffusion flux $($in $\frac{kg}{m^2*s})$ of chlorine through

the cylinder? Chlorine solubility in the

container is $0\mathrm{.}5{10}^3\frac{\text{k}\text{m}\text{o}\text{l}}{m^3*bar}[1$atm$=$

$1\mathrm{.}01325$ bar$]$
