How can I calculate the water level in a grit chamber at average flow and at peak hourly flow. The effluent from the tank flows over a fiberglass, sharp-crested weir that is set at elevation 136.00 ft above sea level (ASL). The average daily flow rate is 2.6 MGD. Assume that all flow must pass through one grit chamber. The dimensions of the grit chamber are 9 ft wide, 30 ft long, and 10.5 ft deep (water depth). The weir extends across the full width of the chamber and find the hydraulic retention time of the grit chamber. HRT at average flow = ______ minutes and HRT at peak hourly flow = ______ minutes
