Explanation of Equation

We say that the equation

tex2html_wrap_inline5

describes the change in the amount of contaminant at time t because reading from left to right, we have the following:
Rate of Accumulation = Rate going in - Rate going out +/- Reaction within the Volume

To learn more about how the equation is constructed and what assumptions are used, select "Formulation of Differential Equations" from the main page.
