A confined aquifer has a source of recharge. Hydraulic conductivity, K for the aquifer is 50 m/day. The piezometric head in two wells 1000 m apart is 45 m and 40 m respectively, from a common datum. The average thickness of the aquifer is 30 m, and the average width of aquifer is 5 km. Compute the rate of flow through the aquifer (assume no dispersion or diffusion through the aquifer).
