A 2 ft diameter well penetrates vertically through a confined aquifer 50 ft thick. When the well is pumped at 500 gpm in 1 day, the drawdown in a well 50 ft away is 10 ft and in another well 100 ft away is 3 ft. The storativity of aquifer is 0.0005. What is the value for transmissivity and drawdown? Note; the piezometric head is 100ft from datum. Combination of thiem & thies equation
