1. Four wells, located 2000 feet apart in a square pattern, are pumped at an average rate of 400 gpm from each well. If the transmissivity of the aquifer is 5000 ft'/day and the storage coefficient is 0.05, find the drawdown at the midpoint between the wells after 1000 days of pumping. Carry out the calculations by assuming that this is a confined aquifer.
