The brine solution is recycled using a series of mixing tanks before being released outside of the tanks. Tank A receives pure water at a rate of 4 L/min. The solution is pumped to Tanks B and C at rates of 2 L/min and x L/min, respectively, from Tank A, which originally contains 500 L of brine solution in which 200 g of salt is first dissolved. At a rate of 4 L/min, Tank B from its original 400 L of brine solution in which 1000 g of salt has been dissolved pumps the solution to Tank C. At a rate of y L/min, Tank C, which originally holds 400 L of pure water, pumps the solution back to Tank B. Meanwhile, Tank C releases z L/min of solution out of the system. a. Determine the values of x, y, and z if the volume of the solution within each tank stays constant throughout time. b. Find out the brine solution's concentration coming out of each tank at time t-8 minutes. 2 L/min TANK B TANKA 4 L/min y L/min Pure water @4 L/min x L/min TANK C z L/min

Question
The brine solution is recycled using a series of mixing tanks before being released outside of the tanks.
Tank A receives pure water at a rate of 4 L/min. The solution is pumped to Tanks B and C at rates of 2
L/min and x L/min, respectively, from Tank A, which originally contains 500 L of brine solution in which
200 g of salt is first dissolved. At a rate of 4 L/min, Tank B from its original 400 L of brine solution in
which 1000 g of salt has been dissolved pumps the solution to Tank C. At a rate of y L/min, Tank C, which
originally holds 400 L of pure water, pumps the solution back to Tank B. Meanwhile, Tank C releases z
L/min of solution out of the system.
a. Determine the values of x, y, and z if the volume of the solution within each tank stays constant
throughout time.
b.
Find out the brine solution's concentration coming out of each tank at time t-8 minutes.
