Hi! hoping you can help me with this question,

I´m doing the hydraulic calculation in the last floor of a building, and the entire building is protected by an sprinkler system. What flow rate should i consider in the calculation for the last 2 connections? 100 gpm each? or a total of 250 pm?

Are these connections consider as an inside hose?

If you are calculating a sprinkler hose allowance, then you calculate 50 GPM per hose connection (furthest one or two hose connections) for the inside hose allowance and the closest hydrant to the riser for the outside hose allowance. See NFPA 13 (2019) section 19.2.6 .

If you are calculating a separate standpipe, then the calculation procedure must be per NFPA 14 section 7.10.
