I sent the preliminary design for the new waste water treatment center described above to the city, and someone did a quick calculation which showed that a lot of acetone would be going into the city sewer. They didn't like the sound of that. So they asked me to re-design the separator, this time, with the added constraint that there be no more than 100lbm per day of Acetone in the stream that gets sent to the city sewer. Assume that the stream leaving Earle Hall is still 250,000lbm every day, and the stream is still 5mass% acetone in water. Also, assume that the stream created to recycle acetone to Earle Hall will still have a composition that is 95 mass % acetone. What will the flowrate of the Recycle stream be, and what will be the mass % of acetone in the of the stream sent to the city sewer?
