The formula to calculate the Average Residence Time (t) is:
\[ t = \frac{V}{Q} \]
Where:
Average residence time is a measure of the average time a particle or substance spends in a particular system or process. It is commonly used in various fields such as chemical engineering, environmental science, and fluid dynamics to understand the behavior and efficiency of systems. For example, in a chemical reactor, the residence time can indicate how long reactants stay in the reactor, which can affect the yield and quality of the final product. Similarly, in environmental studies, residence time can help in understanding the dispersion and dilution of pollutants in natural water bodies.
Consider an example where:
Using the formula to calculate the Average Residence Time:
\[ t = \frac{100}{5} = 20 \text{ s} \]
This means that the average residence time for this example is 20 seconds.
