In Imperial or US customary measurement system, the density is equal to 45.011 pound per cubic foot [lb/ft³], or 0.4168 ounce per cubic inch [oz/inch³] .
WebbFinally, we can calculate the volume of sludge produced per day: Volume of sludge = Mass of sludge / (specific gravity of sludge solids x sludge solids content) Volume of sludge = 1014.3 kg/day / (3.01 x 0.01) Volume of sludge = 33,722.5 L/day = 33.7 m³/day. Therefore, the volume of sludge that must be disposed of per day is 33.7 m³/day.
