At 40 psi, a nozzle with a manufacturer's code of 65155 is designed to produce how many gallons per minute?

The proper nozzle output in gallons per minute (GPM) at a specific pressure is determined based on the manufacturer's specifications for that nozzle. The code 65155 indicates a specific design, typically referring to the nozzle's flow rate and spray pattern, which are calibrated for optimal performance at certain pressures.

For a nozzle with the code 65155, when assessed at a pressure of 40 psi, it is specifically engineered to achieve an output of 1.55 gallons per minute. This precise figure aligns with the standard operating conditions provided by the manufacturer, which are established through rigorous testing to ensure effective and efficient pesticide application.

Understanding the flow rate is crucial for pesticide applicators, as it directly affects the coverage and concentration of pesticide being applied. In this case, the flow rate of 1.55 gallons per minute at 40 psi ensures that applicators can adjust their equipment and application practices accordingly to achieve desired results without over-application or under-application.
