Transcribed Image Text:2. A 12-in well fully penetrates an artesian aquifer 100 ft thick, in which the height of the piezometric surface
is 200 ft.
The permeability coefficient K is 600 gpd/ft?. Two observation wells located at 45 ft and 120 ft from the
pumped well show a difference in drawdown of 7 ft between them.
a) Find the flow rate Q, in gpd, delivered by the well under equilibrium conditions.
b) If the water depth in the first observation well located 45 ft from the pumped well is 190 ft, find the
drawdown sw, in ft, at the pumped well.
c) Find the radius of the cone of influence, in ft.
