What does nozzle code 8002 designate?

• A. 80-degree spray angle with an output of 0.2 gpm
• B. 80-degree spray angle with an output of 0.02 gpm
• C. 20-degree spray angle with an output of 0.2 gpm
• D. 90-degree spray angle with an output of 0.2 gpm

Answer: (A)

Nozzle codes encode two key specs in a compact four-digit form. The first two digits indicate the spray angle, and the last two digits indicate the flow rate in tenths of a gallon per minute. So 8002 translates to an 80-degree spray angle (80) with a flow of 0.2 gpm (02 = 0.2). That combination matches the designation described by the code, making it the correct interpretation. If the angle were different, the leading digits would be different (90 would start with 90, 20 would start with 20). If the flow were 0.02 gpm, the last two digits would not be 02 under this scheme, so that would require a different code.
