Standpipe systems shall be one of the following: (1) Hydraulically designed to provide the required waterflow rate at a minimum residual pressure of 100 psi (6.9 bar) at the outlet of the hydraulically most remote 21/2-in. (63.5-mm) hose connection and 65 psi (4.5 bar) at the outlet of the hydraulically most remote 11/2-in. (38.1-mm) hose station.
65 psi is required at the end of the 100 foot long 1 1/2" hose or at the beginning? I would say at the beginning as that would be the outlet of the hose stations. But would like other opinions.
