Problem 2. A well is located in an unconfined aquifer with a saturated depth of 35 ft prior to pumping.The radius of influence of the well is 900 ft and the radius of the well is 0.25 ft. After pumping is started at 600 ft/d, the drawdown in the well stabilizes at 6 ft. What is the hydraulic conductivity of the aquifer?
