(d) Flat fan. This nozzle is used to make an even broadcast or spot
treatment to a smooth surface. See figure 3-6. Nozzle numbers (usually six digits) on a
flat fan nozzle provide two items of information. The first two digits indicate the spray
angle and the last group of digits indicate the nozzle capacity in gallons per minute
(GPM) at 40 pounds per square inch (psi). A decimal point is placed after the third digit.
See figure 3-7 for an example of interpreting the nozzle number.
