Question $3.$

Question $3(15)$

A stream $n_1^{}$kmo$\frac{l}{h}r$ has a composition $x_{1A}=0\mathrm{.}65,x_{1B}=0\mathrm{.}35.$ It is mixed with a stream $n_5^{},$ with composition $x_{5A}=0\mathrm{.}78,x_{5B}=0\mathrm{.}22.$ The combined stream is $n_2^{}$ and it enters a separator. The bottom stream that exits the separator is $n_3^{}$kmo$\frac{l}{h}r$ and it has a composition $x_{3A}=0\mathrm{.}3,x_{3B}=0\mathrm{.}7.$ The top stream is $n_4^{}$kmo$\frac{l}{h}r$ and it has the same composition as $n_5^{},$ since $n_4^{}$ is split equally into a recycle stream $n_5^{}$ and a product stream with a flow rate of $150$kmo$\frac{l}{h}r.$

$1.$Draw a schematic of the problem, and annotate it with all information, including your unknown values.

$2.$ Solve the problem. Do a degree$-$of$-$freedom analysis before you present results, for each balance $($total$,$ mixing point etc.$).$
