Please also let your colleague know, there are many resources out there for learning hydraulic calculations, using flow and pressure.
It will help us all realize, 1000gpm from 1", thru a k5.6 or 4.2, would be impressive. I recommend, AFSA.. R/ Matt Matthew J.

DO NOT click links or open attachments unless you recognize or trust the sender. The intent of the ITC is to simulate the flow of one sprinkler in order to test the alarm activation. The fire pump has nothing to do with it. There is no measuring the flow from it. However, if you colleague is going to pitot an ITC, call me. I want to watch.

I said its a restricted orifice to represent a sprinkler head flowing. Therefore pump pressure is negligible.
