In a $KN{O}_3$ salt manufacturing facility, $1000k\frac{g}{h}$ of a feed solution containing $20$ wt $\%$

$KN{O}_3$ is fed to an evaporator, which evaporates some water at $422K$ to produce a $50wt\%$

$KN{O}_3$ solution. This is then fed to a crystallizer at $311K,$ where crystals containing $96$ wt $\%$

$KN{O}_3$ are removed. The saturated solution containing $37\mathrm{.}5wt\%KN{O}_3$ is recycled to the

evaporator. Calculate the amount of recycle stream in $k\frac{g}{h}$ and the product stream of

crystals in $k\frac{g}{h}.$
