Problem # 2. A pumping test was made in a sand layer extending to a depth of 15m. The initial groundwater table is located 2 m. below the ground surface. Observation wells were sighted at distances 3m and 7.5m from the pumping well. Using a discharge of 0.4 m^3 per hour, a steady level is attained at the pumping well. The measured drawdowns at the two observation wells are 1.5 m and 0.35 m. respectively. a. Find the hydraulic head at the first observation well. b. Find the hydraulic head at the second observation well. c. Compute the coefficient of permeability.
