Yuri wants to determine the permeability of an aquifer. The aquifer has a test well 300-mm in diameter with two observation wells. A pumping test was conducted for 24 hours with the discharge being held constant at 6,162.8 m^3/day. The first one, 83.03 meters from the test well, has a draw-down of 0.92 meters. The second one, 40 meters from the test well, has a draw-down of 1.44 meters.The static water table penetrates the well to a depth of 28 meters. Determine the radius of influence of the aquifer in meters.
