Re: NFPA 13R & NFPA 14 - (flow rates)
Thanks for the answers Some thoughts Section 7.10.1.3.1.1 of nfpa 14 is under 7.10.1 therefore it only applies to Class I and Class III Systems not to class II. Also, that section is under 7.10 flow rates therefore is not referring to pressure but flow rates. Please correct me if I am wrong. In that example, the apartment complex with the boat storage the part where it is required to be used nfpa 13. If that is the case, then section 7.10.1.3.1.1 would not have needed to add 13R since with 13 would have been good enough, I think. I followed back and found that the 13R was added in 2013 edition of nfpa 14. Therefore, not sure if it was found an example where the solely use of 13R was higher than a Class I and Class III standpipe system. Best Regards.

Re: NFPA 13R & NFPA 14
I could dream up a scenario where a 13R system had a higher pressure requirement (with a lower flow) than a standpipe calculation. Being limited to 4 stories definitely makes this a lot less likely to occur in the real world. It could happen, but I have never seen it here in the real world.

In practice, probably not.
