Question $1.$

It is desired to produce a food product using $5$ stages as shown in figure $1.$ Of the Raw Material the feeding speed is $500k\frac{g}{?}$ hour. Many currents are diagrammed together with known composition values it is marked on it$.$ It is divided into two equal streams, namely E and Golmak. Product P$,80\%$ solid it has the content of the substance, it is the desired end product. A current $K$ oontaining $25\%$ solids at a speed of $200k\frac{g}{h}$ is the by$-$product is obtained. Accordingly, calculate the following.

a$)$ The mass flow rate of product $P?$

b$)$ The mass flow rate of the retuming current A$?$

c$)$ The mass flow rate of the returning current $R?$

Feeding F

$500k\frac{g}{h}o$

$85\%$ water

$80\%K{M}^{{?}^{?}}$
