How do you calculate the total gallons of chemical required?

The calculation for the total gallons of chemical required is determined through a formula that accounts for the concentration of the chemical (PPMV), the flow rate of the water (CFS), and the duration of application in minutes. The correct expression, which uses a standard conversion factor, combines these variables effectively.

In this case, the formula (PPMV x 450 x CFS x minutes applied) / 1,000,000 calculates the total gallons by first converting the parts per million volume (PPMV) into a usable figure for gallons based on the flow rate measured in cubic feet per second (CFS) over a specified time, expressed in minutes. The factor of 450 is used for conversion purposes consistent with the volume of chemical needed to achieve the desired concentration. Finally, dividing by 1,000,000 adjusts the units to gallons, aligning with the need to arrive at a total that reflects the gallons of chemical to be used.

This approach ensures that all necessary parameters for aquatic pest control are considerately integrated in a single formula, which is critical for achieving effective treatment levels in water bodies.
