A non-artesian well is drilled in an aquifer with a fairly horizontal water table. The well (φ = 25 cm) has a discharge of 408 m3 /hr, creating a 250 m wide cone of depression. If the height/depth of the water table is 60 m and the aquifer permeability is 8 m/day, determine the drawdown. Include also diagram or drawing.
