Calculate Required Nozzle Output; Nozzle Selection - Goldacres G6 Crop Cruiser 2 Series Operator's Manual

Calculate the required nozzle output.

2 Calculate Required Nozzle Output

Once an application rate is chosen, the required nozzle output
can be calculated using the following factors:
• Application rate required (eg, 80 l/ha)
• Speed of travel (eg, 12km/hr)
• Swath width (eg, 36m) and
• Number of nozzles on the boom (eg, 72).
Nozzle output can be calculated using the following formulae:
• Nozzle Flow Rate (l/min) = Speed (km/hr) x Swath
Width (m) x Application Rate (l/ha) ÷ 600 ÷ Number of
nozzles
eg, ([12 x 36 x 80] ÷ 600) ÷ 72 = 0.8 l/min for each
nozzle.
An alternative formula is:
• Nozzle Flow Rate (l/min) = Speed (km) x Nozzle
Spacing (cm) x Application Rate (l/ha) ÷ 60,000
eg, (12 x 50 x 80) ÷ 60,000 = 0.8 l/min.
Nozzles manufacturers' downloadable Apps may be useful in helping to
calculate required nozzle rates, as well as displaying suitable nozzles for various
applications.

Calibration – Set & Check Application Rates
Selected & fit the appropriate nozzles for the application.

3 Nozzle Selection

Use a manufacturer's Nozzle Chart (refer to Nozzle Charts on
pages 104 - 107) and/or a manufacturer's App to find & select
the most appropriate nozzles for the application according to:
• Application rate (eg, 80 l/ha)
• Speed of travel (eg, 12km/hr)
• Pressure setting (eg, 300kPa [3 bar])
• Boom configuration & nozzle control system fitted to
the Cruiser - single line, 3TS option, 3TS Pro option or
Hawkeye option.
Nozzles must be selected & fitted for the appropriate application.
Nozzle orifices are subject to wear and must be checked regularly.
Use the Jug Test to check accuracy of application whenever nozzles are changed
or wear.
