Keep reading - 7.10.2.2.2 states, "Common supply piping serving multiple standpipes shall be calculated and sized to provide 100 GPM."
This implies that the procedure is to identify the most remote standpipe and most remote hose connection on that standpipe and size the supply side of the system for 100 GPM to that hose station. Steve Leyton Protection Design & Consulting The foregoing is my opinion only and is not intended to represent the Technical Committee on Standpipe Systems, nor serve as an interpretation of NFPA 14. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of IPA Sent: Monday, June 16, 2008 8:48 AM To: [email protected] Subject: Class II Standpipes I've got a dedicated pump feeding a Class II Standpipe system w/ 1 1/2" hose stations. I need some clarification on how many stations to calc. >From reading NFPA #14 my first guess would be (2) one at each standpipe. NFPA #14 7.10.2.2.1 reads, "Hydraulic calculations and pipe sizes for *each* standpipe shall be based on providing 100 gpm..." But 7.10.2.1.2 states, "Additional flow shall not be required where more than one hose connection is provided." ...and then there is 7.10.2.2.2, "Common supply piping serving multiple standpipes shall be calculated and sized to provide 100 gpm (379 L/min)." How does this fit into the scenario?
