3. A treatment plant consists of eight rectangular final clarifiers, each having dimensions of 18 ft x100 ft with a 16-ft side water depth. Inboard weirs have a total length of 110 ft each. For an average flow of 6 MGD and a peak flow of 25 MGD, calculate the calculate the overflow rate,detention time, and weir loading. Are the clarifiers adequately sized for the flow, and if not, why not?
