A municipal wastewater treatment plant employs three circular primary clarifiers arranged in parallel, following the bar screen and grit removal chamber. The plant receives 12 MGD. Each clarifier is center-fed (water enters at the center and exists at the perimeter).The clarifier radius is 56 ft and depth is 10 ft.What is the hydraulic loading rate (critical velocity) in each clarifier in units of ft3.ft-2.hr-1 ?

A 12 inch diameter well was installed in an unconfined aquifer consisting of a 60 foot thick layer of sand. The water table was 15 feet below the ground surface before pumping of the well began. The well was then pumped at a rate of 30 gallons per minute and the water level in the well dropped to 45 feet below the ground surface after a steady-state condition was reached. The radius of well influence is 4000 feet. a) Calculate the permeability of the sand b) Compute and plot the drawdown surface
