Liquid Chemical Feed Rate Calculator
This calculator can be used to calculate both the per minute feed requirements or total daily feed requirement of a liquid chemical. See below the results for examples. Chemical Reference Table
Per minute example:
Target dose 2.0 ppm
Treated volume 5 gallons (assume this is a per minute flow value of 5 gpm through a pipe)
Assume % active is bleach at 6%
SG (specific gravity) let’s assume 1.1
All the results will be a per minute dosage value of raw 6% chemical to achieve 2.0 ppm in moving fluid so that is 0.02 fluid ounces fed per minute.
Total treated volume example:
For Example: mixing a batch of chemical in a feed tank:
Target dose 10.0 ppm
Treated volume 50 gallons (assume this is a per minute flow value so 5 gpm)
% active, let’s say bleach at 6%
SG (specific gravity) let’s assume 1.1
All the results will be total amount of chemical to add to 50 gallons to make a 10 ppm bulk solution mixture in this case 1.17 fluid ounces is required.
Note: it is most likely easier to make all these calculations in metric for smaller volume or flow values.
