A saline solution with a concentration of 0.5 kg/L is introduced into a tank at a rate of 2 L/min. At the bottom of the tank, the mixture exits at a rate of 2 L/min. After 10 minutes, the inflow is replaced with pure water at the same inlet and outlet rates. If at the initial conditions there are 100 L of pure water in the tank, determine the salt concentration in the tank after 20 minutes of operation. Assumption: the density of pure water and salt solution is the same and the mixing takes place perfectly.
