I'm on the road and don't have my usual reference materials handy, NFPA 13 and 14 fitting tables offer equivalent footage that add up to loss that in that range and higher, depending on flow rate. I've mentioned before that manufacturers tend not to offer friction loss data on their straight hose valves - though a couple do. Keep asking and you'll turn up some information - have you tryed to contact Elkhart yet? I think they may have a loss curve.
Steve Leyton P.S. Who's seen the City Center site in Las Vegas? Staring out at it right now - biggest private-sector dig I've ever seen. They say it will require about 300 fitters for the FP work when it peaks ... -----Original Message----- From: Todd Williams - work [mailto:[EMAIL PROTECTED] Sent: Wed 2/14/2007 10:56 AM To: [email protected] Cc: Subject: hose valve pressure loss Someone in the Forum recently made a reference to friction loss in fire hose valves being around 3 psi with some higher. Is there any documentation for that? I haven't be able to locate any. Thanks. Todd G.
