A grit chamber is used to remove the grit without removing organic material. Assume that grit particles have a diameter of 0.2 mm and a specific gravity of 2.65 (sand, silt and clay); and organic material has the same diameter and a specific gravity of 1.15. Assume drag coefficient (Cᴅ) of 10, dimensionless constant related to particle characteristics (k) of 0.06 and Darcy-Weisbach friction factor (f) of 0.03.
Determine the surface overflow rate.
