3. a well 12-in in diameter penetrates vertically through a 60 foot thick confined aquifer. after a long period of pumping at a rate of 350 gpm, the drawdowns in the wells 57 ft and 148 ft from the pumped well were found to be 12 ft and 7.4 ft respectively. what is the transmissivity of the aquifer? what is the approximate drawdown in the pumped well? assume that the initial piezometer level is 108 feet above the datum.
