Pumping test was carried out in a layer of soil extending to a depth of 28 m. The initial position of water table is located 4 m below the ground. Observation wells were sighted 33.5 m & 97.5 m from the pumping well. Water is pump at 248.4 m3/hr and when steady level was attained, the drawdowns at the observation wells were observed to be 1.1 m and 0.54 m, respectively. Compute the coefficient of permeability in m/day. CHOICES A. 64.82 m/day B. 71.49 m/day C. 71.49 m/day D. 78.09 m/day
