5. 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. a. Determine the height of water at the farthest observation well. b. Compute the coefficient of permeability in m/day. c. Determine the transmissibility (drainage capability) of the soil in m²/day.
