A settling tank is designed to remove

discrete particles $0\mathrm{.}5mm$ drameter,

relative density $($specific grawity$)$ of $1\mathrm{.}01$

from water at $20C.$ Assume idea

settling conditions, determine the

removal of sphencal discrete piarticles

$0\mathrm{.}2mm$ drameter, relative density g $1\mathrm{.}01$

by thes tank.
