An unconfined aquifer is known to be 32 m thick below the water table. A constant discharge of 2 cubic metres per minute is pumped out of the aquifer through a tubewell till the water level in the tubewell becomes steady. Two observation wells at distances of 15 m and 70 m from the tubewell show falls of 3 m and 0.7 m respectively from their static water levels. Find the permeability in mm/s of the aquifer. a.3.28 x 10^-1 b.4.68 x 10^-1 c.2.58 x 10^-1 d.1.18 x 10^-1
