A community of 15,000 capita and fire demand of 35 L/s for six hours is to be served by a 50 cm diameter well. The well is constructed in a confined aquifer with a uniform thickness of 15m and hydraulic conductivity of 100 m/d. Two observation wells are installed at radial distance of 50 m and 150 m. The drawdowns in the wells are 1.7 m and 1.3 m respectively. Find: a) the discharge of the well. b) water consumption (l/c/d). c) the power needed to lift the water to the ground surface if the original piezometer level is 20 m below the ground surface.
