Figure $1.$ Batch settling data for Question $2($a$).$

$($b$)$ The data in Table were obtained from a batch settling test using the method of

Talmage and Fitch, where $C$ is the solids concentration and $V$ is the velocity.

Table $1.$ Batch settling data for Question $2($b$).$

$($i$)$ Draw the sedimentation flux curve.

$($ii$)$ Calculate the maximum solids concentration of the feed a thickener of $20m$

diameter can handle if the feed rate is $2\mathrm{.}8\frac{m^3}{m}in$ and the underflow

concentration is to be $650k\frac{g}{m^3}.$
