Find out more about the advantages of flat fan nozzles and different application examples. Now, youll be able to determine the flow rate (gpm), with the following equation: Finally, youll be able to select a nozzle size that will give the flow rate (gpm) determined above. 0 Overlap of flat-fan nozzles is required because the outer edges of the spray patterns have tapered or reduced volumes. For technical support please contact the CFAES Helpdesk. 111 0 obj <> endobj University of Georgia Cooperative Extension programming improves people's lives and gets results. If a nozzle with a different performance size were used, it would also be apparent that the influence of viscosity also depends on the performance size of the nozzle. The types which are commonly used for ground application of agricultural chemicals are flat-fan, even flat-fan, and cone nozzle. Check spray overlap by spraying clean water onto a flat surface (concrete) and observing drying patterns.

Columns 4 and 5 give the flow rate of nozzles in gallons per minute and ounces per minute, respectively, at different pressure settings. Step 5. With a larger droplet size, drift reduction pre-orifice nozzles can replace conventional flat-fan 80 and 110 degree tips in broadcast applications where spray drift is a problem. What size tip should be selected? If you look at Column 6, choose 8 mph ground speed, the nozzle we selected will spray approximately 15 gallons per acre (14.9 gpa shown on the chart) at 8 mph travel speed and 40 psi spray pressure. Flow rate: On the influence on the flow rate, the most precise information is available. The nozzle to select from the catalogs (based on water) would be calculated as follows: 15 GPA (28% N) x 1.13 (conversion factor from Table 4) = 16.95 GPA (water).
