Consider a 2000 liters large tank holding 1000 liters of pure water into which a brine water solution of salt begins to áow at a constant rate of 6 liters/min. the solution inside the tank is kept well stirred and is áowing out of the tank at a rate of 6 liters/min. if the concentration of salt in the brine entering the tank is 0: 1 kg/liter. (i) set up the initial value problem equation and solve the problem. (ii) determine when the concentration of salt in the tank will reach 0: 05 kg/liter.
