A waste water plant uses a gift chamber to settle out sand particles. Water flows at a rate of 100 gal/min through the chamber, which is 2 m in height and has a volume of 100 m^3. Calculate the minimum-sized sand particle that would be removed in the chamber. To be removed, the particles must settle the depth of 2 m during the period the wastewater spends in the chamber (dT=V/Q). Sand density is 2.65 g/cm^3, water density is 1.0 g/cm^3, and the viscosity of water is 0.01185 g/cm*s.
