A bankrupt chemical firm has been taken over by new management. On the property they found a 20,000-m3 brine pond containing 25,000 mg · L−1 of salt. The new owners propose to flush the pond into their dis- charge pipe leading to the Atlantic Ocean, which has a salt concentration above 30,000 mg · L−1 .
What flow rate of fresh water (in m3 · s−1 ) must they use to reduce the salt concentration in the pond to 500 mg · L−1 within one year?
