Three geometrically identical wells constructed in a confined aquifer are located on the corners of an equilateral triangle, whose side is equal to 40m. Water is pumped out from the wells such that the drawdown in each well is 2 m. The permeability and depth of the aquifer are 3 x 10^-5 m/s & 18 m respectively. The diameter of the well is 3 m. The total discharge was obtained from the well.
