Two rectangular clarifiers(sedimentation basins), each 30 ft long, 15 ft wide, and 10ft deep, settle a combinedtotal of 0.40 mgd following alum coagulation. The effluent channelshave a total weir length of 60ft in each basin. Calculate the detention time (in hours),horizontal velocity of flow (ft/min), and rate offlow over the outlet weir (weir loading, in gpd/ft).
