Calculation Tools

Nozzle Selection Tools

CP Quick Calc will help determine which tips or orifices best suit application goals.

The Aerial section of the quick calc provides suggested settings with estimated pressures using the data that you provide. This gives a starting point that can then be entered into the USDA droplet models to give an idea of what the probable droplet spectrum will be. Pattern testing is the next step in verifying that your setup is performing as expected. Operation S.A.F.E. clinics offer Pattern Deposition Analysis to help guide and calibrate equipment to optimum performance. These clinics help you find optimal swath and droplet size. Also, the clinics help solve equipment problems before starting a new season.

The Ground section of the quick calc will provide recommended orifice/tip combination for the selected nozzle with an estimated pressure and expected droplet classification with the setting.

 

CP Aerial Nozzles

A set of variables must be known to make a selection:

  • Airspeed
  • Swath
  • GPA (Gallons Per Acre)
  • Amount of Nozzles in use

If working in Meters for swath and Liters per Hectare, conversions to Feet and Gallons per Acre will need to be done before using online tools.

Narrow down the nozzle options using the CP Quick Calibration tool. This will filter all known settings and show a suggested Orifice/Tip size with an estimated pressure for use. All pressure settings that fall between 30-60psi will be shown.

USDA Droplet Models

Droplet spectrum, or spray quality, is an important part of aerial application. Droplets that are too small may not reach the target and could drift. Droplets that are too large may not give adequate coverage. The USDA models are an excellent starting point for applicators to choose nozzles. All CP nozzles are tested at the USDA facility to gather this useful information and data collected is put into the models.

 

Once and Orifice or Tip size has been determined, enter the information into the USDA-ARS Atomization models to view the droplet spectrum data. 

Models are available in Low Speed and High Speed.

 

 

CP Ground Nozzles

A set of variables must be known to make a selection;

  • Ground Speed
  • Spacing
  • GPA (Gallons Per Acre)

If working in Meters for swath and Liters per Hectare, conversions to Feet and Gallons per Acre will need to be done before using online tools.
