Suppose that a tank with a capacity of 24 gallons initially contains 16 gallons of pure water. A salt solution containing 3 pounds of salt per gallon is allowed to run into the tank at a rate of 16 gal/min, and the well stirred mixture is then removed at a rate of 12 gal/min, as shown in the figure. The process is continued until the tank is filled (see figure below). Fluid In w'. 0 Mixture 1. Write an intial value problem for w, the total weight (in pounds) of salt in the tank. The concentration is W= Fluid Out w(0) = 2. Determine the concentration of the salt solution in the tank at the end of the process. Ibs/gal.
