Consider a problem of three connected tanks T1 , T2 and T3 containing 200 gallons of water each. Initially, Tank 1 contains pure water while the tank 2 and tank 3 contains 50lb and 100 lb of salt respectively. The liquid circulate between the three tanks at the rate of 10 gallons/min. Tank T1 Tank T2 Tank T3 200 gal 200 gal 200 gal The amount of salt in T1, T2 and T3 represented by Y1(t), Y2(t) and Y3(t) changes with time t due to flow of liquid and continuous stirring. 1. Calculate the amount of salt in each tank after 10 min. 2. How long will it take to get equal amount of salt in each tank.
