In a batch thickener, an aqueous sludge containing 35% by volume of solids (SG ¼ 1:6), with an average particle size of 50 mm, is allowed to settle. The sludge is fed to the settler at a rate of 1000 gpm, and the clear liquid overflows the top. Estimate the minimum tank diameter required for this separation.
