Tanks A, B, and C are all filled with 1000gal of water. The workers are instructed to dissolve 2000lbs of salt in each tank. By mistake, 3000lbs of salt were dissolved in tank A, another 3000 in tank C, and nothing in tank B. You want to bring all compositions to 5% of the specified value of 2lb/gal. If the units are connected A-B-C-A by 50 gallon per minute (gpm) pumps, plot the concentrations of salt in each of the tank as a function of time using numerical methods (Euler, Heun or RK4, choose which method would suit best). How long would it take to bring the compositions to within 5% of the specified value of 2lb/gal ? Will there be a difference if 1500lbs of salt were added to tanks B and C each? Mention the considerations used in modeling
