A well pumping at Q$=77,000$ ft$3/$day has observation wells at distances $10,40,150,$

$300,$ and $400$ ft away. After $201\mathrm{.}6$ minutes of pumping the drawdowns observed at the $5$

monitoring wells are: $15\mathrm{.}1,9\mathrm{.}4,4\mathrm{.}4,1\mathrm{.}7,$ and $0\mathrm{.}25$ ft$.$ Estimate T and S and the radius of

influence of the well.
