Note:
If the collected nozzle spray does not
meet the quantity in the Nozzle Flow Rate Chart
(page 37) , check the nozzles, hoses, and fittings
for leaks, damage, or wear; clean or replace the
spray nozzles if needed.
Nozzle Flow Rate Chart
Use the nozzle flow rate charts determine spray
nozzle performance:
•
Nozzle flow rates at different spray-system
pressures
•
Worn or damaged spray nozzles
The following chart is based on the nozzle capacity
information chart provided with permission from
TeeJet® Technologies. Use the chart below or
reference the TeeJet® Technologies website to
determine if the flow rate of the sprayer nozzle is
within the specified flow rate (+/– 10%).
Note:
The chart information below is based on the
machine spraying water at 70 ° F (21 ° C).

Determining Application Rate
Use the example results of the calculated speed,
spray width, and nozzle capacity to determine the
application rate.
Note:
The application rate may also be determined
by using the Nozzle Flow Rate Chart (page 37) ,
along with the chemical manufacturer’s label of
recommendation.
The examples below are based on the following
information:
•
Average ground speed = 8.4 kph (5.2 mph)
•
Spray width = 2.7 m (108 inches)
•
Number of nozzles = 2
•
Nozzle capacity = 3.0 L/min (0.8 gpm)
Note:
The numbers 6 and 600 are constants used in
the formulas shown below.
Liter per 100 m 2 Application Rate
Single nozzle capacity (Lpm) x Number
of nozzles x 6 L
Speed (kph) x Spray width (m)
=
100 m 2
2.99 Lpm x 2 x 6
8.369 kph x 2.743 m
=
1.563 L/100 m 2 (1.5
qt/1,000 ft 2 )
Liter per Hectar Application Rate
Single nozzle capacity (Lpm) x Number
of nozzles x 600 L
Speed (kph) x Spray width (m)
=
hectar
2.99 Lpm x 2 x 600
8.369 kph x 2.743 m
=
156 L/hectar(16.7 gal/acre)
Note:
The numbers 544; 136; and 5,940 are
constants used in the formulas shown below.
