hi guys as per the title does anyone know where i can find this value in NFPA i know it exists but i cant seem to find it

Hi Guys, My local code (which is based on NFPA), it says the coverage for fire hose reel is 30m maximum. But it doesn't specify if this includes the hose stream allowance or not. When I was in Australia we were allowed 30m hose reel coverage plus 6m stream allowance, i.e if your hose...

So structural engineer is being an ass and keeping his slab at 350mm, therefore I have no choice but to install my floor drain inside the concrete slab (due to local code floor drain neck can't exceed 500mm and due to slab being 350mm by the time this is installed below the slab i would of...

Hi all, your comments helped. i have now reduced the pipe size to meet my demand of 22.2 l/s with velocity at 1.81 m/s currently/now running calculations to see the affects of this on my frictional pressure loss

itdepends you are right, but i think i am confused if i have a tank with a 150mm outlet with the given head and cd value, then the flow is the flow, its irrelevant what the demand is ?

vt2012 - you are spot on. so how do i reduce the velocity down ? in that 150mm pipe which is giving 80 l/s at 4.52m/s to 35 l/s at 2m/s

Guys thanks for your responses. I know what my demand, pipe Ø and velocity need to be. That was not my question, my question is what will be the actual velocity in a 150mm pipe for a tank with a given head of 2m, and that I got as 4.52m/s. And that is not full flow, full flow would be when...

Guys, Your input would be very much appreciated. The following problem is building services related, best person to answer - hydraulic engineer, fire engineer, fluid mechanics expert Situation: Water storage tank at level Z, with effective head at outlet 2m (20kPa). Outlet is re-entrant tube...

Hi All, I probably should have done more research before posting this but oh well what is the price difference between a Breaching Inlet vs. Sprinkler booster assembly. In Middle East all I saw were breaching inlets whereas in Australia I haven't come across this term however there are...

As per title, lowest point in the wet sprinkler system ?

Hi All, I am trying to work out how to fire protect glass walls, and in my case a glass wall enclosed with glass doors, which swing. I cant seem to find anything in NFPA. What I have got so far is to protect with sidewall sprinklers above the glass door. NFPA 101 says to have sprinklers on...

Hi All, So as per 8.6.4.1.1.1 (nfpa 13 2013 ed.) the sprinkler can only be 12in from the ceiling. what about in case of structural beams that are running along the roof which are 900mm in depth? Do the sprinklers go 12in below the beam ?

Hi All, I am a mechanical engineer from Australia, working in Dubai where we US standards. I just moved here few months ago. I am confused about NFPA 13 8.5.2.1.1 (2015 ed) protection area of coverage What I want to ask is the areas given in Table 8.6.2.2.1 are they maximum or minimum ? I...
