Three input streams are fed into an evaporation chamber to produce

an output stream with the desired composition.

Stream A: Liquid water, fed at a rate of $20\mathrm{.}0$ cm$3/$min $($density is $1$

g$/$cm$3)$

Stream B: Air $(21$ mol$\%$ O$2$ and the balance N$2)$

Stream C: Pure oxygen, with a molar flow rate one$-$fifth of the molar

flow rate of stream B$.$

The output gas is analysed and it is found to contain $1\mathrm{.}5$ mol$\%$ water.

Draw and label a flowchart of the process, and calculate all unknown

stream variables.
