How to Calculate Spray Impact
When working with spray systems, such as the kind used in paint applicators or pesticide sprayers, you may notice a slight difference in the precision and accuracy of a new nozzle tip versus an older tip. This is because the quality of a nozzle can change dramatically with the age of the nozzle. An older, corroded nozzle will not spray as accurately as a newer nozzle. This difference becomes important in jobs where accuracy is vital, such as painting. Use a formula to calculate spray impact of a nozzle Does this Spark an idea?

Figure out the density of the liquid being used. This factor is the mathematical constant because it will not change from nozzle to nozzle. We will call the liquid density of this equation C.
-
2
Determine the flow rate of the nozzle that you are using. We'll call the flow rate F.

3
Figure out the liquid pressure being used in the nozzle. We'll express this number as P.

4
Calculate the square root of the liquid pressure (√P).

5
Multiply C by F. Multiply the answer by the square root of P (√P). Expressed as an equation, this would look like A=CXFX√P.
