A well pumping test was carried out to determine the bulk permeability of a confined aquifer. The aquifer was overlain by a clay layer 4m thick, the depth of the aquifer was 20m, and the initial piezometric level in the aquifer was 2m below ground level. After a period of pumping when steady state conditions had been reached, the following observations were made: pumped flowrate q=1.637 li/s well radius=0.1m drawdown just outside well = 2m drawdown in piezometer at 100m distance from well = 0.2m. Determine the bulk permeability of the aquifer in m/s . Use the format for your answer 1.111 x 10^(-4).

Question
A well pumping test was carried out to determine the bulk permeability of a confined aquifer. The aquifer was overlain by a clay layer 4m thick, the depth of the aquifer was 20m, and the initial piezometric level in the aquifer was 2m below ground level. After a period of pumping when steady state conditions had been reached, the following observations were made:
pumped flowrate q=1.637 li/s
well radius=0.1m
drawdown just outside well = 2m
drawdown in piezometer at 100m distance from well = 0.2m.
Determine the bulk permeability of the aquifer in m/s . Use the format for your answer 1.111 x 10^(-4).
