We wish to flash distill an ethanol-water mixture that is \(30.0 \mathrm{wt} \%\) ethanol and has a feed flow of \(1000 \mathrm{~kg} / \mathrm{h}\). Feed is at \(200.0^{\circ} \mathrm{C}\). The flash drum operates at a pressure of \(1.0 \mathrm{~kg} / \mathrm{cm}_{2}\). Find \(\mathrm{T}_{\text {drum }}\), weight fraction of liquid and vapor products, and liquid and vapor flow rates.
