Correction at 1 PSI it is .02 GPM. But you get the idea. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O. Box 882136 Steamboat Springs, CO 80488 Tel: 970-879-7952 Fax: 970-879-7926
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Thom McMahon Sent: Thursday, November 05, 2009 3:22 PM To: [email protected] Subject: RE: 5.62 K Factor The difference between a 5.6K orifice and a 5.62K is only .20 GPM @ 100 PSI, so unless your calculating discharge at very high pressures who cares. Conversely at 1PSI the difference is only .01 GPM. See we start using computers that carry every calculation to 3 decimal places and that is the level of accuracy we expect, until you realize we started with a lot of assumptions, multiplied those by fluffy calculations, and then applied an accuracy of .001?

The real question though, as someone mentioned yesterday, is why are you being required to "prove" a pipe schedule system?
