In this applet, you are provided with a representation of a pond with an inflow stream and an outflow stream. Using the available text fields, you can control several parameters, and observe the results.
V is the volume of the pond in cubic meters.
Q is the rate of flow of both the input and output streams in cubic meters per second. After you have set the parameters, click the OK button to see the results. On the schematic cross section of the pond, relative concentrations are shown by shades of gray, with darker grays representing higher concentrations. The points on the graph are listed in the Relative Concentration chart. Progress in the direction of the final concentration limit is shown in the Progress chart and graph.
