A well 12‐in in diameter penetrates 108 ft below the static water table. After a long
period of pumping at a rate of 350 gpm, the drawdowns in wells 57 ft and 148 ft from the
pumped well were found to be 12 ft and 7.4 ft, respectively.
(a) What is the transmissivity of the aquifer?
(b) What is the approximate drawdown in the pumped well?
