Do not rely solely on speedometers as an accurate measure of ground speed, especially on older tractors. For broadcast applications, W = nozzle spacing (distance between two nozzles on the boom) in inches.

Remember that one specific type of nozzle will not be best for all applications. Drift is influenced by many factors which are discussed in detail in two OSU Extension publications (Bulletin 816 and FABE-525) listed in the references at the end of this publication. 0000008943 00000 n Calibration is easy, and there are many ways to do it. There are different diluents used for spray application. Checking nozzle catalogs, the Spray Systems TX-4 and Delavan HC-4 cone spray nozzles have a rated output of 0.20 GPM at 60 psi. Determine "GPA " - First select the application rate in gallons per acre (GPA) used.

If a specific nozzle size is not available, try changing the travel speed and determine the new flow rate needed. Similar calculations can be made using the equation below to come up with other GPM (flow rate) and PSI (pressure) combinations to satisfy the required 15 gpa application rate: In this example, reducing the pressure to 25 psi alters the spray quality to Coarse, violating the label recommendation.

University of Georgia Cooperative Extension programming improves people's lives and gets results. For example: You want to spray a pre-emergence herbicide at 15 gpa, at a speed of 8 mph. The correct nozzle tip size depends on an application rate in gallons per acre (GPA), ground speed (MPH), and effective spray width of each nozzle (W). Luckily, most nozzle manufacturers catalogs have charts showing which nozzle type will be best for a specific job. From measurement results, it can be concluded that flat fan nozzles with a larger flow rate are more angularly stable than those with a smaller performance size. Now we proceed with the process to determine the appropriate size of the nozzle. We want to find out what the new travel speed (MPH) should be to achieve 15 gpa (GPA). Selecting the right type and size of a nozzle is not sufficient to end up with accurate, effective and efficient application of chemicals sprayed. 0000301448 00000 n Alternatively the nozzle itself can be in motion to provide complete coverage. There may be situations where the charts will not provide information associated with your sprayer setup (nozzle spacing) and operating conditions (travel speed and spray pressure). nozzle spray angle nozzles pressure practical network tips specifications Column 6 gives gallons per acre application rate at different travel speed settings. Smaller drops are produced at pressures from 30 to 60 psi, increasing the likelihood of drift.
