A chemical is added at the beginning of a water treatment plant at a target concentration of 8 mg/L in water. The water treatment plant provides water to a community of 340,000 people and the average water consumption in the city is 130 gallons per capita per day (gpcd). If the chemical is available in a concentrated solution that is 23% (w/w; i.e., 23 lb of chemical/ 100 lb of solution) with a specific gravity (SG) of 1.23, find the quantity of chemical solution that will be required daily (in ft' and gallons). It is desired to keep the chemical in 750 gallon tanks and have at least two weeks of chemical storage available. What is the minimum number of tanks that will be required?

![A chemical is added at the beginning of a water treatment plant at a target concentration of 8 mg/L in
water. The water treatment plant provides water to a community of 340,000 people and the average
water consumption in the city is 130 gallons per capita per day (gpcd). If the chemical is available in a
concentrated solution that is 23% (w/w; i.e., 23 lb of chemical/ 100 lb of solution) with a specific
gravity (SG) of 1.23, find the quantity of chemical solution that will be required daily (in ft and
gallons). It is desired to keep the chemical in 750 gallon tanks and have at least two weeks of chemical
storage available. What is the minimum number of tanks that will be required?
