Answer in three decimal places please
A permeability pumping test was carried out
in a confined aquifer with the piezometric
level before pumping is 2.18 m. below the
ground surface. The aquiclude (impermeable
layer) has a thickness of 5.98 m. measured
from the ground surface and the confined
aquifer is 7.5 m. deep until it reaches the
aquiclude (impermeable layer) at the bottom.
At a steady pumping rate of 17.8 m³/hour
the drawdown in the observation wells. were
respectively equal to 1.60 m. and 0.42 m.
The distances of the observation wells from
the center of the test well were 18 m. and 34
m. respectively. Compute the depth of water
at the farthest observation well.
