What about showing him the equivalent length chart in NFPA 13 for gate valves?

OS&Y valve cutsheets don't have a friction loss chart because the loss is so minimal. Does anyone have any ideas on how to explain this to an OSHPD inspector, he have already told him this but he is just stuck on wanting to know the "flow rates" Rocci Cetani III, CET Senior Designer Water-Based Fire Protections Systems Layout, Nicet Level III Northern California Fire Protection Services Inc. 16840 Joleen Way Bldg.
