A tank contalns 40 gal brine for which the concentration is initially 3 lb/gal of salt. A brine solution is pumped into the tank at the rate of 5 gal/min. and the mixture, kept uniforrby stirring, runs out at the same rate. If the concentration of the solution flowing in is 2 lb/gal, a) determine the amount of salt in the tank at anytime t, b) how much salt is present after 10 min? c) after a long time? 12. A tank contains 80 gal of pure water. Brine solution with 2 Ib/gal of salt enters at 2 gal/min, and the well-stirred mixture leaves at the same rate. Find a) the amount of salt in the tank after half an hour? b) determine the limiting value for the amount of salt in the tank after a long time, and c) how much time must pass before the amount of salt in the tank reaches 80% of this limiting value? 13.
