60 cm diameter well is being pumped at a rate of 1360litres/minute. measurements in a nearby test well were made at thesame time as follows. At a distance of 6 m from the well beingpumped, the drawdown was 6 m, and at 15 m the drawdown was 1.5 m.The bottom of the well is 90 m below the ground water table.
(a) Find out the coefficient of permeability.
(b) If all the observed points were on the Dupuit curve, whatwas the drawdown in the well during pumping?
(c) What is the sp. capacity of the well? (d) What is the rateat which water can be drawn from this well?
