1.A well of radius 0.4 ft produces water from an unconfined aquifer with K = 12 ft/day. The well is located 850 ft from a large water body that acts as a constant head boundary. If the saturated thickness of the aquifer at the water body is 75 ft, what is the maximum production rate of the well?
2.Estimate the total cost and cost per linear foot for furnushing and driving steel-sheet piling for construction of the basement of a building, 150 by 240 ft. the piles will be 22 in. wide, 18 ft. long, and weigh 40.3 Ib/Lin ft. the piles will be driven in pairs to full penetration into soil having normal frictional resistance.
