A pumping well is to be used to maintain a lowered water

A pumping well is to be used to maintain a lowered water table at a construction site. The site is a square, 50 m on each side, and the 25 cm diameter well is located at the center of the square. K=1×10^-5 m/s or .864 m/day. The bottom of the aquifer is approximately horizontal at a depth of 20 m below the ground surface. Under natural conditions, the water table is nearly horizontal at a depth of 1 m below the ground surface and the unconfined aquifer is uniformly recharged at a rate of w= .06 m/day. During the construction period, the water table must be lowered a minimum of 5 m on the site. Assuming steady state conditions, compute the pumping rate required.
