I believe this is spelled out in the NFPA 14 handbook. You will need to do 2
sets of calculations. Where you only have 2 standpipes, you calculate the 750
gpm. When you get down to the level with 3 standpipes, you do another calc
that goes to 1000 gpm.

I would think it depends on your license type. Call your distributor and
see if they can determine if you need to do anything special.

takes on stuff like this. It helps when the plan reviewer is actually a very
nice person. He acknowledges that they take a different interpretation, and

I was informed from the AHJ that they would accept a "technical question"
answer from NFPA only if he agreed with it. Otherwise, it would take a formal
interpretation. As I said, some days you just really have to love what you do.
Thankfully I do.

I think the issue is that ESFR sprinklers can’t be less than 8’.
You can do <6’ with SSU/P sprinklers as the standard references baffles in

I didn't even read that. NFPA 13 uses nominal k-factors. There is no
difference in a K17 and K16.8. Look in Chapter 6. You will see anything
with a range of 16.0-17.6 is to be calculated at k16.8

Dig into the areas of 13 about that. I don’t have the reference off hand, but
you have provisions to use sprinklers in different orientations for the exhaust
duct. So, just put a pendent sprinkler in the horizontal position.

I’ve had some large demand systems….5000 gpm and more. They always had
specified (3) 2500 gpm pumps for the 5000 gpm systems. I had one 9000 gpm
system that had (4) 3000 gpm pumps. The idea was that if any one pump was
done, the system would still be maintained with adequate pumping capabilit
