Problem 2: Steam is used to desalinate a brackish stream at a flow rate of $850\mathrm{kg}/\mathrm{s}$ and an inlet temperature of $30.\mathrm{C}$. The feed water contains $2.5\%$ Salt. Saturated Steam 6 bar of $80\%$ quality is used as heating media and exits as saturated liquid water at 4.8 bars. If $60\%$ of the water is vaporized and the pressure in the desalination vessel is 1.013 bar, determine the flow rate of the steam. Problem 3: Seawater stream at a flow rate of $1050\mathrm{kg}/\mathrm{s}$ and inlet temperature of $30^{\circ }\mathrm{C}$ is desalinated to produce freshwater. The feed water contains $4.1\%$ Salt. Saturated Steam at a flow rate of 300 $\mathrm{kg}/\mathrm{s}$ at 5 bar of $80\%$ quality is used as heating media and exits as saturated liquid water at 4.8 bars. Determine the flow rate and compositions of the vapour and brine streams.
