A well of 0.4 m diameter fully penetrates a 25 m thick confined aquifer of coefficient of permeability of 12m/day. The well is located in the center of a circular island of radius 1 km. The water level at the boundary of the island is 80m. At what rate should the well be pumped so that the water level in the well remains 60 m above the bottom?
