For example, using Example A from the previous pages ….
• Row spacing = 2.4m
• Number of rows = 1
• Number of nozzles = 14
• Speed = 6 kph
• Ideal pressure 12 bar
• Tier 1 target rate = ?? L/ha
Using the formula left….
300
(target rate) x
7.5
(speed) ÷ 600 ÷
40
(number of
nozzles) x
3.0
(row spacing) x
2
(no. of rows)
= 0.56
Litres per minute per nozzle.
Once the flow rate per nozzle is known select the most
appropriate nozzle from a flowrate chart for the nozzle
being used. Flowrate charts are available from relevant
nozzle suppliers. Croplands supplies and recommends
the ALBUZ ATR Hollow Cone Nozzles for the Quantum
Mist Sprayers.
Pictured left and overleaf are screenshots taken from
a small spreadsheet program freely available from the
Croplands Web Site or Croplands Customer Service titled
“ALBUZ QM Nozzle Selection Worksheet” which makes
it much quicker to calculate nozzle requirements. For more
nozzles refer to the Croplands Optima buyers guide.
In the example left the
correct nozzle
for Tier 1 is the
ALBUZ Brown operating at 7 Bar.
In the sample below, the
correct nozzle
for Tier 2 is
the ALBUZ Yellow operating at 7 bar. Note the formula
requires 0.84 L/min, and the nozzle flowchart shows
0.86 L/min. This nozzle with a marginal decrease in
pressure will meet our requirements.
Across the spraying season the variables (such as rates
and speeds) may often change. With a well setup system
small variations will be easily accommodated. Larger
variations may require a change of nozzles.
