A 10 m-thick sandy, silt deposit overlies an impermeable stratum. The water table is at a depth 3 m below the ground level. During a pumping-out test, at steady state, water is being pumped out of a 400 mm diameter well at the rate of 6000 liters/min. At the observation wells, at radial distances of 3.5 m and 25.0 m, the water levels dropped by 2.5 m and 1.2 m respectively. What would be the height ( ) in meters of the water in the pumping well?

GEOTECHNICAL

A 10 m-thick sandy, silt deposit overlies an
impermeable stratum. The water table is at a depth
3 m below the ground level. During a pumping-out
test, at steady state, water is being pumped out of a
400 mm diameter well at the rate of 6000 liters/min.
At the observation wells, at radial distances of 3.5 m
and 25.0 m, the water levels dropped by 2.5 m and
1.2 m respectively. What would be the height (
) in meters of the water in the
pumping well?
