The flow rate per atomiser/nozzle is calculated using the following formula
Flow rate per atomiser/nozzle (l/min) =
Band width (m) x Vehicle speed (kph) x Application Volume (l/ha) / 600
Note: Metric units must be used for this formula
For example:
Two Undavina CDA 400 spray heads and a Spraymiser CDA 1200 on the rear on an
ATV travelling at 6 kph applying 40 l/ha of spray mix.
First calculate the flow required for each Undavina CDA 400 as follows
Band width = 0.4m
Vehicle speed = 6 kph
Application volume = 40 l/ha
Flow rate per Undavina CDA 400 (l/min) = 0.4 m x 6 kph x 40 l/ha / 600 = 0.16 l/min
Set each head to 0.16 l/min or 9.6 l/hr
Now calculate the flow required for each atomiser on the Spraymiser 1200 as
follows
Number of atomisers = 2
Band width = 1.2 m
Vehicle speed = 6 kph
Application volume = 40 l/ha
Flow rate (l/min) = 1.2 m x 6 kph x 40 l/ha / 600 = 0.48 l/min
Divide the flow rate by the number of atomisers 0.48 / 2
Set each atomiser to 0.24l/min or 14.4l/hr
