Question $7$

$($Max $10)$

A batch settling test on a slurry gave the following results, where the height $z$ in meters between the clear liquid and the suspended solids is given at time t hours. The original

slurry concentration is $250k\frac{g}{m^3}$ of slurry. Determine the velocities of settling and concentration and concentrations and make a plot of velocity versus concentration.
