A water cleanup is stripping vinyl chloride from contaminated ground water at $25oC$ and $850\mathrm{.}00mmHg$ using a counter$-$current, staged stripper. Feed is $5ppm($molar$)$ vinyl chloride. Outlet water that contains $0\mathrm{.}1ppm($molar$)$ is required. Inlet air used for stripping is pure. For a liquid flow rate of $L=1\mathrm{.}0$kmo$\frac{l}{h},$ determine the following:

Minimum Gas flow rate $V_{\text{m}\text{i}\text{n}}^{\text{'}}$ in Kmo$\frac{l}{h}$

$($b$)$ If $V^{\text{'}}=2\mathrm{.}0V^{\text{'}}$min, use a McCabe$-$Thiele Diagram to determine the number of equilibrium stages needed.

Note: Scales on your $y$ and $x$ axes should be different. Calculate two points to plot the straight lines.

What is the concentration of Vinyl chloride in the outlet gas?

The Henry's law constant at these conditions is $H=1243\mathrm{.}84$ atm$/$mole$.$ frac $)=(Hx$
