Question
A permeability test was carried out from a well that sunk through a surface
layer of loose sand. Figure below shows the arrangement of pumping wells, together
with relevant dimensions. Initially, the piezometric surface (ground water table) was
located at a depth of 2.5m. When steady state was achieved at a pumping rate 38.5 m^3/hr, the following drawdowns were observed.
Pumping well, d0 = 3.64m
Observation well, d1=0.96m
Observation well, d2 = 0.48m
Calculate the coefficient of permeability of the sand in m/hr
