  1. Anthony works at a plant that makes a solution for brining hotdogs. A tank with a capacity of 2000 liters originally contains 1500 liters of fresh distilled water. Two pipes pour different mixtures of brine into the tank. The big pipe pours 1 kg of salt per minute at a rate of 6 liters per minute. The smaller pipe pours a mixture containing 2 kg of salt per minute at a rate of 4 liters per minute. Assume the salt and water are well mixed.

  1. If the mixture flows out of two pipes at a rate of 5 liters per minute each, what is the amount of salt in the tank at any time . What is the amount of salt at 10 minutes? Does solution reach a steady state of salt and if so, what is it? Graph the solution.
  1. Anthony accidentally shuts off one of the outflow pipes and doesn’t notice. When will the tank overflow and how much salt will it contain? Graph the solution.
  1. He notices that the tank is overflowing and turns off the big pipe. How long will it take for the tank to return back to 1500 liters of the mixture. What will happen in the long run? Graph the solution.

A 2000 gallon tank initially contains a mixture of 750 gallons of water and 100 gallons of salt. Water is added at a rate of 8 gallons per minute, and salt is added at a rate of 2 gallons per minute. At the same time, a well mixed solution of "brine" is exiting at a rate of 5 gallons per minute. What percentage of the mixture is salt when the tank is full?

A 110 gallon tank initially contains 5 lbs salt dissolved in 60 gallons of water. Brine containing 1 lb salt per gallon begins to flow into the tank at the rate of 3 gal/min and the well-mixed solution is drawn off at the rate of 1 gal/min. How much salt is in the tank when it is about to overflow? (Round your answer to the nearest integer.)
