Help with Bresnan Cellar Nozzle

[FireCritic]

A question from an engineer here, slightly impaired by lack of knowledge. Should be an easy question, although I will be the judge by the number of views before an answer.

I need to know what the nozzle pressure and flow are for a Bresnan cellar nozzle is attached to a 2 1/2" hose. Thanks in advance for the answer.

Update:

I found some information. We have an Akron 9 outlets. From what I have found it is 250 gpm's at 100 psi.

Do any of you have sop's on Cellar nozzles. I have not used one, or heard of one being used in a very long time.

Our cellar nozzle is 265gpm @ 100psi. IF we ever used it, we cut a 8-10" in the floor and drop the nozzle down. Never used it on an actual fire, just in training.

Good trick is the hand it to a new guy and say "Hey...check out this new nozzle", then charge it, but not at 100psi. Quite funny...if you're far enough away.

I might just have to try that!

Works even better when you attach it to the deck pipe and point it in the air. Hey sub give me 100 on this line....they never see that green open light on the deck pipe valve...

Just a remider. You need a shut-off valve back one length of hose. Kind of useless down the hole with the nozzle, yet you want the ability to shut it down without the air traffic. Stay Safe

Thanks for the reminder. I guess if we used it often we would keep a ten foot section with a shut off on it attached to the nozzle. We don't use it often so we will need to remember it.

Thanks

We got a rookie REAL good years ago with one. We told him it was for flow testing hydrants so he screwed it on a 2 1/2" port an then charged the hydrant.

We actually used a cellar nozzle today at a stubborn basement fire. I won't get into the details, but essentially there was an extremely high fire load in the basement, and the floor above was no longer safe to be on or below. I'll say one thing, using the nozzle sure created some serious steam coming back out of the basement windows, but didn't extinguish the seat of the fire. Filling the basment with class A foam helped...

Everyone hates losing a house, but you can't save them all - especially when the odds are stacked against you. We didn't hurt any firefighters, and no one was home at the time. (I need to keep telling myself this stuff) First time we've actually had to back out of a structure in the time I've been on the department, and everyone hates being beat. At least the fire wasn't on Thanksgiving...

Just out of curiosity what would be the flow from an 1 1/2" sized Bresnan? Anyone know? I'm assuming that the same 100 psi nozzle pressure would be used. Thanks in advance.
