A 180 mm diameter well witch penetrating in soil at depth 7 m to extrude the ground water from a land have an area as shawn in figure. the total decline in head of well is 5 m, the hydraulic conductivity is 10 m/day, the storag coefficent of medium sand soil is 20, use two pumps of flow rate 100 cubic meter per day to pullout the ground water from the land. How long should the pumps stay active to draw the ground water from the land? 110 25 m 20m 30 m -30 m
