Question 3
A pumping test was performed in a well penetrating a confined
aquifer to evaluate the coefficient of permeability of the soil in
the aquifer. When equilibrium flow was reached, the following data
were obtained:
Equilibrium discharge of water from the well = 800 l/min, Water
levels (h1 and h2) = 7 and 9 m at distances from the well (r1 and
r2) of 25 and 65 m, respectively and the thickness of aquifer = 8
m. Determine the coefficient of permeability of the soil in the
aquifer
