The data from a settling column analysis of a dilute suspension of flocculating solids are

listed below. Plot the removal percentages at the corresponding coordinates of depth and

time. Sketch lines representing $15\%,30\%,45\%,60\%,$ and $75\%$ removals through the data.

Estimate the overall removal for a settling tank $6\mathrm{.}0$ ft deep with an overflow rate of $6\mathrm{.}0/50$

fpm$.$
