Of course! I know this is unorthodox thinking, especially for an NFPA 14 maestro. But I figured out quite a few years ago how to get not only K, but the Q and P that goes with it for a flowing outlet with only two pieces of information; the nominal diameter and the coefficient of discharge. And after the twists and turns and showing off and stepping in it this weekend I wanted to take my best shot at being the anybody with a decent K for a 2.5 inch hose valve, as Vince asked. So "In the same way as a nominal 1/2" sprinkler..." K=113.85, if the C of D is .61, final answer.
