K=50 for 100 psi @ 500 seems to always work out in the field. -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Steve Leyton Sent: Thursday, April 05, 2012 11:57 AM To: sprinklerforum@firesprinkler.org Subject: RE: k -- WHAT? Um, Ron? According to that chart a 2.5" angle valve will flow 9.9gpm at 100psi. I don't think that's quite in accordance with HW. If you are flowing 250 through the valve at 100psi, it has a K of 25.0, no? But they can flow more ... K at 350gpm/100psi would be 35 ... What are you trying to do?
