Couipaiy 27, A large tank is partially filled with 400 L of fluid in which 5 kg of salt is dissolved. Brine containing 0.25 kg of salt per liter is pumped into the tank at a rate of 20 Lmin. The well-mixed solution is then pumped out at a slower rate of 15 L/min. Find the number of kilograms of salt in the tank after 30 minutes.

15. Consider a two tank system pictured below. Suppose tank A contains 100 gallons of water in which 120 pounds of salt are dissolved initially. Suppose tank B has 100 gallons of water in which zero pounds of salt are dissolved initially. Liquid is pumped into and out of the tanks as indicated in the figure; the mixture exchanged between the two tanks and the liquid pumped out of tank B are assumed to be well mixed. How many pounds...

Salt water flows at a constant rate of 6 L/min into a tank that initially held 100 L of salt solution in which was dissolved 0.15 kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the solution entering the tank is 0.03 kg/L. a) Dtermine the mass of salt in the tank after t min. b) When will the concentration of...
