Question $3$: $(20$ marks$)$

a$)$ Consider a $50cm$ Krebs hydrocyclone used for an experiment that vielded results in Table $2.$ The hydrocyclone was set up for Solid $x$ in water. The solids' density is $2870k\frac{g}{m^3}$ and the masses of particles on each sieve $($in grams$)$ for the feed and product streams are given in Table $2.$

Table $2$: Data from a hydrocyclone experiment:

$\backslash$table$[[($ancion$).\frac{m^3}{h},$Feed,product $A,$product B$],[\backslash$table$[[$stream$],[$Volumetric flow rate of slurry $($suspension$),\frac{m^3}{h}$
