But since friction head with turbulent (sprinkler) flow is proportional to the velocity squared, and the data from Ron Greenman's link says 'K Value for use in the formula hf=k(v^2/2g)', and the velocity varies as the flow, wouldn't the K Value give us the friction loss 'curve' we are looking for, as opposed to an average over a range?

I started to say before getting overly precise (but that horse has left the barn), it might be helpful to keep in mind that the K valve on a sprinkler is NOT a constant at different flows. It is an AVERAGED result for flows from 7 psi to 100 psi.
