All, Has anyone ever taken time to find the coefficient of discharge for the UL rain test nozzle ( https://www.shopulstandards.com/ProductDetail.aspx?UniqueKey=27488)?
The Type 3R test I'm doing requires 5 PSI of water pressure on a straight pipe. Using the Pitot Gauge equation, it seems to me I should be able to figure out how much water is being used every hour. I suppose I could simply spray into a bucket to learn the flow rate in GPM or LPM, but my nozzles are still on order and have not arrived yet.
