A 2‐ft diameter well penetrates vertically through a confined aquifer 50 ft thick. When the well is pumped at 500 gpm, the drawdown in a well 50 ft away is 10 ft and in another well 100 ft away is 3 ft. (a) What is the approximate head in the pumped well for steady‐state conditions, and what is the approximate drawdown in the well? (b) Compute the transmissivity. Take the initial piezometric level as 100 ft above the datum.
