One of the main problems I've had working at A/E MEP firm is getting a G*d D@#n hydrant flow test that is accurate or current. I have to beg PM's to ask the client, there is never money in the budget for us to do it, owner's act like I asked them for the heart and blood of their first born.

Is this common or have a worked for a garbage firm?

My thought would be to base off of the calced fire flow, at 20 PSI and on the NFPA 921 10% off demand and work backward to a static/churn and design a "theoretical curve" that might work. I know this is kind of tail wagging the dog, but hopefully my next employer will get us information when we request it.
