(10 Points) A contractor is trying to estimate the distance to be expected of a drawdown
of 4.81 m from a pumping well under the following conditions:
Pumping rate = 0.0280 cubic meter per seconds
Pumping time = 1066 d
Drawdown in observation well = 9.52 m
Observation well is located 10.00 m from the pumping well
Aquifer material = medium sand
Aquifer thickness = 14.05 m
Assume that the well is fully penetrating in an unconfined aquifer.
