What proportion of spherical sand particles 0.01 mm in diameter with specific gravity (SG) = 2.65

will theoretically be removed in an ideal, horizontal?flow settling basin 3 m deep with a surface area

of 900 m2 if the flow is 80,000 m3/d and the water temperature is 20°C? (Use ? = 1.0 x 103 kg/m?s

and ? = 1000 kg/m3 for the water.)

Answer is 8.7% explain how this number come up 8.7percent
