Simple sprayer calibration

[Stuart J]

Morning all,

My brain isn't working properly so please help me out.
What is the formula for a simple sprayer calibration?
Here's my example:
6m boom with 12 nozzles
Each nozzle is 1.2l/min

What speed do I need to go to give 200l/ha?

 

[mushnt grummmble]

About 7km hour at 3 bar

12 nozzles gives 14.4l/min or 864l/hr, divided by 200l/ha you need to do 4.32ha/hr. 43200m2 divided by 12 equals 3600m/hr or 3.6km/hr

600 x jug test 1 minute into jug
divide by speed
divide by nozzle spacing

google sprayer calibration charts and download,job sorted

 

[Stuart J]

600 x jug test 1 minute into jug
divide by speed
divide by nozzle spacing

It's the speed I'm trying to work out.

work it out backwards you know the application rate etc

As above, 03 nozzle, 3 bar, smidge over 7k

12 nozzles gives 14.4l/min or 864l/hr, divided by 200l/ha you need to do 4.32ha/hr. 43200m2 divided by 12 equals 3600m/hr or 3.6km/hr

It's the speed I'm trying to work out.

3.6km/hr

3.6km/hr

Multiply it by 0.5 nozzle spacing and you will not be far out.

spot on, i was working on 12m sprayer width so 7.2km/ hr
