Problem 3. A well of 0.4 m diameter fully penetrates a leaky confined aquifer having a hydraulic conductivity of 20 m/day and a thickness of 30 m. The leakage coefficient of the confining layer is 0.05 per day. A drawdown of 1m is recorded at a distance of 100 m from the well. What is the steady-state rate of pumping of the well? Values of the Hantush well r function Wu, B are given in the table (on the other side of the sheet).
