A 0.5-m diameter well fully penetrates an unconfined aquifer, which is 40.0 m thick. The drawdown at the pumped well is 10 m and the hydraulic conductivity of the aquifer is 0.2 . 10-3 (m s-'). If the flow is steady and discharge is 0.01 (mºs-'), determine the drawdown at a site 50.0 m from the well. Draw-down (m): 5.0 8.6 18.6 30.0 A wastewater treatment plant treats 1000 (mº

An engineer has been asked to investigate illegal pumping of groundwater from an unconfined aquifer. The maximum withdrawal rate for the well has been set by the State Water Resources Board at 30,000 ft/day. The water table far from the well is 20 f below the surface. The depth to the confining bed is 50 ft. Two observation wells have been installed near the pumping well to assess the groundwater withdrawal rate. The first well is located 100 ft from...

An unconfined aquifer has an initial thickness of 15.80 m. The initial water table is horizontal and located 4.7 m below the ground surface. A 15-cm diameter well is driven to the bottom of the aquifer and pumped at 3000 Lpm until steady state conditions are achieved. At this time the drawdown at the well is 4.35 m and the drawdown in an observation well located 850 m away is 0.12 m. (a) Make a sketch that defines the problem....

A lagoon with volume 1,000 m3 has been receiving a steady flow of a nonconservative pollutant with reaction rate of .20/day at a rate of 100 m3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 100 mg/L. Assume completely mixed conditions. If the input waste concentration suddenly decreased to 10mg/L, what would the concentration in the effluent be 10 days later?

Question 4 (20 points) A lagoon with volume 1.200 m' has been receiving a steady flow of conservative waste at a rale of 100 m'iday for a long enough time to assume steady state conditions apply. The waste entering the lagoon has a concentration of 10 mg/L. Assuming completely mixed conditions. a) What would be the concentration of pollutant in the effluent leaving the lagoon? (10 points) b) If the input waste concentration suddenly increased to 100...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
