Mixing Problems F. A tank is initially filled to capacity with 250 L pure water. At t=0, brine containing 2 g/L salt is pumped into the tank at a rate of 25 L/min. The well-mixed solution is pumped out at a larger rate of 50 L/min. Determine the concentration of the salt inside the tank after 5 min. G. A tank containing chocolate milk initially contains a mixture of 460 gallons of milk and 40 gallons of chocolate syrup. Milk is added to the tank at the rate of 8 gallons per minute and syrup is added at a rate of 2 gallons per minute. At the same time, chocolate milk is withdrawn at the rate of 10 gallons per minute. Assuming perfect mixing of milk and syrup. Determine how much syrup will be in the tank over a long time
