A feed stream flowing at $1000k\frac{g}{h}$ contains $20wt\%KN{O}_3$ and $80wt\%H_{2}O.$ The stream enters an evaporator $-$ crystallizer$/$filter process to produce a solid product that contains $4wt\%H_{2}O.$ The evaporator produced a mixture that contains equal amounts of the $2$ components. The liquid stream from the crystallizer$/$filter unit, consisting of $0\mathrm{.}6kgKN\frac{O_3}{k}g{H}_{2}O,$ is recycled. Draw and label the process flowchart and calculate the recycle to fresh feed ratio.
