Three wells are located at the vertices of an equilateral triangle where the distance between each well is 100 m. The well radius of each well is .076m. The wells all extend through the 40m thick confined aquifer which has a hydraulic conductivity of 80m/d and a storage coefficient of 4.2x10-4. Two of the three wells are pumping wells while the third well serves only as an observation well. Pumping well one begins pumping at noon at a rate of 1500 m3/day, and pumping well two begins pumping at 2pm at a rate of 2500
m3/day.
A. Calculate the drawdown in the observation well at 4pm.
B. Calculate the drawdown in pumping well one at 4pm.
C. Calculate the drawdown in pumping well two at 4pm.
