Assignment no. 3 Problem # 1. A 300 mm diameter test well penetrates 24 m. below the static water table. After 24 hours of pumping at 69 liters/sec. The water level in an observation well at a distance of 96m from the test well is lowered 0.60m. And the other observation well at a distance of 34m from the test well, the drawdown is 1.2m. a. Compute the coefficient of permeability of the unconfined aquifer in m/day. b. Compute the transmissibility of the unconfined aquifer in m2/day. C. Compute the transmissibility of a confined aquifer 8m. thick below the unconfined aquifer in m2/day.
