A pond contains V gallons of water and M grams of pollutant. Polluted
water, containing ρ grams per gallon of the pollutant, enters the pond at the rate of a gallons per hour. The mixture flows out at the same rate of a gallons per hour, and we assume that the pollutant is always perfectly mixed with the water in the pond (that is, equal volumes of water contain the equal amount of pollutant everywhere in the pond). Write the differential equations for the amount of pollutant in the pond, as a function of time, and investigate the long-time behavior of 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 24 gallon tank is filled with pure water. Water which has a concentration of 6g of salt per gallon flows into the tank at a rate of 2 gallons/min, and the mixture is stirred to a uniform concentration. Water also leaks from the tank at the same rate, 2 gallons/min. Find a differential equation describing the rate of change of salt in the tank. Hint: The concentration of salt in the tank is S(t)/24, where S(t) is the total...
