The net annual operating cost (AOC) for a water treatment filtration plant for a semi-conductor fabrication line was estimated to be $1.5 mil­lion per year. The estimate was based on the $200,000 per year cost of a 1-MGD plant. The exponent in the cost-capacity equation is 0.80. (a) What was the size of the larger plant? (b) Build a spreadsheet to answer the same question. (c) If the plant manager has limited the AOC to $1 million per year, use your spread­sheet to determine the maximum MGD size plant that can be planned.
