  wants to determine if it has enough groundwater resources to supply its population at the U.S. average
  rate of 1,400 gallons per person per day. Drilling has determined that there is a 20-foot thick aquifer
  under the entire city with a porosity of 20 and a specific yield of 5. The city geologist has
  determined that the sustained yield is one-fiftieth of the specific yield. Up to how many gallons per
  person per day can this city pump water without lowering the water table? (There are 640 acres in a
