The Water Environment Federation (WEF) recommends that the linear flow-through velocity in a
wastewater clarifier should be less than to 0.020 m/s to prevent scour. Using ẞ = 0.06 for sticky particles
and a Darcy-Weisback friction factor of 0.03, estimate the specific gravity of a 200 μm diameter particle
that will be scoured at the recommended velocity. Express your answer in kg/m³ and round to the
nearest integer.
