Nozzles are important because:
• Control the amount – GPA.• Determine uniformity of application.• Affects the coverage.• Influences the drift potential.

Calibration!!!!
Ensuring that the spray output is what it is supposed to be!

![Page 15: Calibrating Sprayers for Droplet Size…. ….according to the label](https://reader035.fdocuments.us/reader035/viewer/2022062410/568161e6550346895dd20a16/html5/thumbnails/15.jpg)
Calibration/Nozzle Selection:
• What is the first step?• Use label to select the
– application volume– product rate
• Choose an appropriate travel speed - MPH
• Effective width of application– nozzle spacing
• Calculate GPM – Flow rate per nozzle
• Select the correct size of nozzle!
![Page 16: Calibrating Sprayers for Droplet Size…. ….according to the label](https://reader035.fdocuments.us/reader035/viewer/2022062410/568161e6550346895dd20a16/html5/thumbnails/16.jpg)
Flow Rate Equation:
GPM GPA x MPH x W5940
Equation
• Calculates for amount of flow from one nozzle
• Represents the size of nozzle to put on the sprayer
See Page 173, TeeJet Catalog 50A

GPM Example Solution:
GPM GPA x MPH x W5940
594020x12x7.5GPM

Selecting the proper nozzle….
• Calculate GPM (formula)• Look under GPM column• Match to pressure-psi• Choose the size needed• Operate at given pressure
and speed used in formula to achieve GPA
