A triple effect parallel feed evaporator is fed at $20000k\frac{g}{h}$ of an aqueous organic solution contains $7$ mass$\%$ solids. The temperature of the feed is $27C$ and the feed split on a $40$:$30$:$30$ basis. The final products must contain $30\%$ solids. The fresh saturated steam enters the first effect at $180$ kPa $($abs$)$ while the third effect is operated at $20$ kPa $($abs$).$ The flow rate of the steam is $5000k\frac{g}{h}.$ It can be assumed that the BPR$\text{'}$s can be neglected. The heat capacity can be assumed to be constant for all liquids at $4\mathrm{.}19k\frac{J}{k}g.$ K$.$ The overall heat transfer coefficients in each effect are: $U_1=2930$;$U_2=2326$ and $U_3=1744\mathrm{.}5$ W$/$m$^2.$K$.$ Determine:

Do only one iteration.
