An unconfined aquifer has a hydraulic conductivity of 25 mm/sec. There are two observation wells 458 ft apart. Both wells penetrate the aquifer to the bottom. In one observation well water stands 28.8 ft above the bottom at a radius of 687 ft, and in the other it stands 22.5 ft above the bottom. What is the discharge per 100 foot wide strip of the aquifer in square ft per day?
