A 0.75-m radius well fully penetrates a 24-m thick unconfined aquifer and is pumped at a rate of 10 L/s (or 864 m3 /day). The drawdown in an observation well 30 m from the pumped 3 well is 1.6 m after a long period of pumping. The drawdown in another observation well 60 m from the pumped well is 1.1 m after the long period of pumping. Determine a) the hydraulic conductivity of the aquifer, b) the expected drawdown in the pumped well, and c) the radius of influence (i. e., when there is no drawdown so the head is 24 m) of the pumped well
