A tank contains salt water of volume V L with a salt concentration of C1 g/L. Furthermore, the salt solution with a concentration of C2 g/L was flowed into the tank at a rate of Fv L/min. mixing is considered perfect. If the flow rate of the salt solution out of the tank is the same as that going in, a. Draw a schematic of the process and determine the mathematical equation for the concentration of salt in the tank as a function of time. also determine the boundary conditions. solve the mathematical equation. b. if it is known that V = 800L, C1 = 1 g/L, C2 = 3 g/L, and Fv = 5 L/min, find the concentration of salt in the tank after 40 minutes c. If a salt concentration of 2 g/L is desired in the tank, after how many minutes must the feed water flow be stopped?
