Private Applicator Agricultural Pest Control Practice Test

Flow rate is encoded in the nozzle code. The leading portion identifies the nozzle family, while the trailing digits show the flow rate in tenths of a gallon per minute. For code 8002, the trailing digits are 02, which means 0.2 gallons per minute at the standard test pressure. So the flow rate expressed is 0.2 gpm. Keep in mind this is a rated flow at a specific test pressure (often about 40 psi); actual flow in the field depends on the operating pressure and nozzle wear.
