Any idea what assumptions would need to be made? I know the pitot reading out of the 2.5" that we did measure would be slightly less than what a typical reading would be without opening the 4". But is there an assumption we can make for the 4" flow nozzle being open and add the two together to...
We did pitot both ports, but only at 2 out of the 7 locations that were tested that way...
I understand there would need to be some assumptions made in order to calculate the fire flow, I just need to determine what assumptions those are and report those.
Thank you!
This may be a stupid question, but we recently did some hydrant testing where we knew the previous test results showed an issue with getting adequate pressure drop from the static to residual pressure. Therefore, we opened the 4" port to test the flow of hydrants where we were able to. However...
