Bunce’s farm has a 10 L water tank fed by a stream running from Boggis’ Chicken Ranch. Water from the stream flows into and out of Bunce’s tank at a rate of 10 L/minute which keeps it well-mixed. One day Bunce finds out that Boggis has been dumping chicken manure into the river which adds Salmonella to the stream at an unknown concentration of a mcfu/L (Note: mcfu is a unit of measurement for bacteria standing for “millions of colony forming units”). At the time of his discovery, Bunce measures the concentration of Salmonella in his tank to be 1 mcfu/L and one minute later measures it again to be 2 mcfu/L. Use these measurements to determine the concentration of Salmonella in the river and the limiting concentration of resulting Salmonella in Bunce’s tank.
