The correct volume of spray is the sprayer application rate multiplied by the number of acres. Example. You want to spray a 12-acre field and your sprayer applies 20 gallons per acre. Gallons of spray mixture = application rate (gallons per acre) × area to spray (acres) Therefore, put (20 × 12 =)
What is a boom on a sprayer? : a pipe with attached nozzles for distributing spray from a tank.
How do you make a sprayer boom?
How high should sprayer booms be? This is an 80 degree angle nozzle designed to operate at 30 inches above the target for the recommended 100 percent overlap coverage. In this case, the target was weeds, so the boom needed to be 30 inches above the average weed height. Spraying 30 inches above the target will subject the spray to more drift.
What is the function of knapsack sprayer? A knapsack is a type of sprayer that disperses liquid through a hand-held nozzle that is attached to a pressurised reservoir carried on the operators back. Knapsack sprayers can be used to apply liquids such as fertilisers, herbicides and fungicides for example and is suited to spot treating areas.
How is boom spray calculated? To calculate spray application rate (L/ha) For general broadcast spraying, the swath width is equal to the number of nozzles multiplied by the nozzle spacing. For band spraying the swath width is equal to the total of all the band widths.

Nozzle Spacing The most common nozzle spacings are 20 and 30 inches. Many sprayers are now being converted from 30 inch to 15 inch spacings. The 30-inch spacing is used for the lower application rates (7 to 10 gallons per acre) and the 15-inch spacing for the higher application rates (14 gallons per acre and higher).

How do you choose nozzles?
Selecting Your Nozzle Size You’ll want to determine the nozzle flow rate at gallons per minute (gpm). To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W).
