How is total gallons per CFS calculated?

The calculation of total gallons per cubic feet per second (CFS) using the provided formula takes into account both the concentration of the pesticide in parts per million weight (PPMW) and the application duration.

In this context, the formula involves converting PPMW, which is a measure of the amount of the active ingredient in water, to a volume metric necessary for understanding how much pesticide is being applied over time and flow rate. By multiplying PPMW by 3,744, you effectively convert it into a total application metric over a specified time (in minutes) and flow rate.

The division by the product of the active ingredient concentration (in pounds per gallon) multiplied by 1,000,000 accounts for scaling down the units to ensure that the calculation reflects adequate proportions of pesticide application relative to flow. This is crucial in aquatic pest control practices where water movement and concentration levels directly influence effectiveness and environmental safety.

This method allows applicators to precisely determine how much total pesticide volume is needed in relation to the flow rate of water in aquatic environments, ensuring effective and safe pest control. Such calculations are paramount in maintaining the balance between controlling pest populations and minimizing ecological impact.
