PROBLEM 2 A well is constructed to pump water from a confined aquifer. Two observation wells are constructed at distances of 100 m and 1000 m respectively. Water is pump from the pumping well at a rate of 0.2m³/min. At steady state, the draw down is observed as 2 m and 8 m respectively in the farthest and the nearest observation wells. Diameter of the test well is 1m. a. Determine the hydraulic conductivity in cm/s if the thickness of the aquifer is 20 m. b. Determine the drawdown in the test well.

PROBLEM 2
A well is constructed to pump water from a confined aquifer. Two observation wells
are constructed at distances of 100 m and 1000 m respectively. Water is pump from
the pumping well at a rate of 0.2m3/min. At steady state, the draw down is observed
as 2 m and 8 m respectively in the farthest and the nearest observation wells.
Diameter of the test well is 1m.
a. Determine the hydraulic conductivity in cm/s if the thickness of the aquifer is 20 m.
b. Determine the drawdown in the test well.
