Test header sizing / 2000gpm pumps 2

[ContractorDave]

Is there a table somewhere that would tell me the required pipe size and number of hose valves for a given pump volume? I know I can ask most of the engineers here and they'd put pencil to paper and come up with something pretty quick but I'd like to have a reference document. I have a design with 2000gpm 120psi pumps showing only a 6" test header line. Since this pump is to flow 150% I'm having a nagging feeling about 6". Attached is a partial pdf of the dwg. You'll note that TP7 is a 6" test line.
Appreciate your thoughts.

I apologize in advance for the pdf. I'm doing something wrong I guess. I've never been able to properly add a file. This one was only 6 or so kb.

check 5.19 and table 5.25 nfpa 2003

Per NFPA 20, 07, Table 5.25 A, test header pipe is 8" for a 2000 gpm pump. BUT if the header is more then 15' away from the fire pump then the size increases to 10" or u can also do a calculation for the size, section 5.19.3.4.

.... and there it is. I'm not sure how I missed that considering it's not some small blurb. Thanks cdafd and LCREP.
