You have been asked to evaluate the ability of a horizontal flow, gravity grit chamber to remove a 0.020 cm particle under different environmental conditions. The particle density is 1.83 g/cm³. In cooler months, the wastewater temperature is 12 ℃. In hotter months, the wastewater temperature is 25 ℃. The depth of the grit chamber is 1.0 m. The detention time of the wastewater in the grit chamber is 60 seconds. Assume the density of the wastewater is 1.000 kg/m³. Assume Stoke’s Law applies.
