Extracted text: A confined aquifer (permeable soil) is shown. This aquifer has a source of recharge located as shown. The hydraulic conductivity of the aquifer is 40 m/day with a porosity of 25%. The piezometric (head) surface in the two observation wells 1200 m apart are at elevations 65 m and 60 m, respectively from the common datum. The aquifer has an average thickness of 25 m and an average width of 4 km. Determine the value of flow rate of water through the aquifer in m3/day. Determine the value to the seepage velocity in m/day. Determine the value of the time of travel from the head of the aquifer to a point 1km downstream in days.
