Ready to order some fresh new nozzles for your sprayer? Can't remember how many of each nozzle that you need? Here is a quick little calculation to determine how many nozzles you need to order.
(Boom Size in Feet)*(12)=(Boom Size in Inches)
(Boom Size in Inches)/(Nozzle Spacing)=(Number of Nozzles Required)
Then add 4-10 nozzles for spares.
So for 100ft spray boom with 20inch nozzle spacing the calculation would be.
100 * 12=1200 inches
1200 / 20=60 nozzles + Spares
