Tank 1 (T1) initially contains 100 gallons of pure water. Tank 2 (T2) initially contains 100 gallons of water in which 150 lb of salt are dissolved. The inflow into T1 is 2 gal/min from T2 and 6 gal/min containing 6lb of salt from a seawater inlet (an outside source). The inflow into T2 is 8 gal/min from T1. The outflow from T2 is 2 + 6 = 8 gal/min to a retaining pond outside. The mixtures are kept uniform by stirring. Find and plot the salt contents x1(t) and x2(t) in T1 and T2 using eigenvalues and eigenvectors.
