A pumping test was carried out in a confined aquifer 15m thick overlain by an impermeable layer 30m thick. Rate of pumping was 0.12 m3/s, drawdowns in observation wells located 15m and 30m from the center of the pumping well were 1.60 m and 1.40 m respectively, from the initial groundwater level. The diameter of the pumping well is 0.40m. Determine the coefficient of permeability
