NOZZLE SELECTION
Use the following formula to covert pounds per acre to gallons per minute (gpm):
EXAMPLE - The desired output is 100 lbs of nitrogen per acre. In order to get 100 lbs of nitrogen you need to apply
357 lbs of 28% nitrogen solution per acre. 357 lbs per acre of a solution that weighs 10.65 lbs per gallon equals
33.53 gallons per acre (GPA). Select a nozzle that will provide 33.53 GPA at your desired system pressure.
