Q.1.23 A field pumping test was conducted from an aquifer of sandy soil of 4 m thickness confined between two impervious strata. When equilibrium was established, 90 liters of water was pumped Observation wells Ap Test well Ime ち=6m Impermeable stratum = 3 m hz = 2.7 m h, = 2.1 m Confined aquifer H, = 4 m Impermeable out per hour. The water elevation in an observation well 3.0 m away from the test well was 2.1 m and another 6.0 m away was 2.7 m from the roof level of the impervious stratum of the aquifer. Find the value of k of the soil in m/sec. (
