Western States Fire Protection's Ben Stewart breaks down remote area calculations for sprinkler system layout using Autosprink
I wish nick was still here
ill always be here in spirit buddy
@@I_WasHere thanks for the upload hope you are doing well, man!
When performing hydraulic analysis of sprinkler systems with inside fire hose stations, i.e., fire hose cabinets, should you include the fire hose cabinets in the analysis (50 gpm each for a total of 100gpm) or not include it and just add the 100gpm in the sprinkler demand in the last step?
Where exactly in the code was it that indicates you need to choose the sprinkler closer to the mains when including sprinklers?
This guy is a genius at explaining this! He makes it so simple! 👍🏼
Please have him explain more!!!! This was helpful!
Hi, I have a question. When performing hydraulic analysis of combined sprinkler systems, shiuld you include the fires hose cabinet in the analysis ? I have been looking for answer to this question, i hope you could help.
Post more!! He’s a great instructor
“Gonna get like 3 views” lol. Got a lot more than that!! This is helping me with school. Thank you!! :)
When you perform hydraulic calculations on a combined system, do you include the 1-1/2 dia. fire hose cabinet? If so, do you use 65psi and 100gpm as the residual pressure and flow, respectively in the analysis??
Hi Nick. I watched your videos and it had me interested to study NFPA-13 because of your video. I have a question please, so once you had identified or drawn the design area, does it mean the flow rate per sprinkler head is equal to the: (design area multiplied by density) divided by (the number of sprinkler heads enclosed in the design area you just drawn)?
it would be the coverage of the sprinkler head, not the area. so it would be the density of the calculation multiplied by the coverage of the sprinkler head. i suppose you could divide it by the number of sprinkler in your area to get a general idea, but it may not be accurate as the coverage per head may change based on your layout potentially being atypical in design
Nick, since pipe closer to water source has higher flow, can I/we install lower K rating head? This way water doesn't squirt everywhere when activate. thk
Man more videos plz im about to start at freedom fire pro in northwest arkansas and im not sure if they have this im about to start on a whole new crew all new pepple even foreman is gonna be new
Hi Nick its me again. I watched your videos and it had me interested to study NFPA-13 because of your video. I have a question please, so once you had identified or drawn the design area, does it mean the flow rate per sprinkler head is equal to the sprinkler system water demand or requirement (design area multiplied by density) divided by the number of sprinkler heads enclosed in the actual area you just drawn or work out?
hi Nick thanks for this video very helpful but sorry for this stupid question, what is the benefit of having a reduced design area?
Its less sprinklers to take into the calc, so its less water of a water requirement that has to be accounted for your design area. You should take a reduction any time its possible to do so. For instance i recently had a calc that with standard response heads and a 1500 sqft remote area did not work hydraulically. But when designed with quick response sprinklers and a reduced area size, the calculations did work
@@I_WasHere ok i had to think deeply on that, but still have no idea why the standard response heads did not work hydraulically on 1500 sqft. but the quick response did. Though on the lesser water requirement part, i think i understood, and it is that by looking thru the Density/Area curve characteristic, as the area is reduced, the density tends to increase, but even though increase, you still gonna end up having a reduced sprinkler water demand, as area is multiplied by density. I know this will be demanding but would appreciate if can correct me if im wrong.
Great video. Thanks for posting it
Nice video, well explained,thanks for sharing
Legendary video son!!
Thank you for this!!! Hydraulics make a little more sense. Would love to see more.
Good but also wrong on couple discussions..
Hi Nick, can i ask a question?, how you determine the remote area or most demand area of the building, if the building had a floor have no partition and the floor area is all about 7k sq. ft?. (ordinary 1 hazard) can i use my remote area is 1500 sq.ft or 7k sq. ft? thanks
you can. the size of the remote area has no direct correlation with the size of the system. the only determining factors would be hazard and structure. so youre only taking into account the density and ceiling height if the ceiling height is low enough that you area able to use a remote area reduction and that your hazard is low enough to use a reduction
@@I_WasHere, there is a reduction relative to the ceiling height??😮 can you send me the reference sir?
Not sure if you're still taking his classes, but if so I would love for more videos. These have been really helpful and he keeps things very simple and easy to comprehend!
Okay, after getting the remote area we are to solve the head loss, no? Do we have to solve all the head loss in the entire building or just from the tank to the remote area? hope my question makes sense.
Just for head loss in the remote area. As far as the tank thing, i personally havent had much experience with tanks and someone can correct me if im wrong, but i believe youre only calculating through the pipe directly from the water source and your remote area
Thank you so much for the reply.My classmate thinks that we need to calculate the head loss for the entire building. God bless
can i ask again?, how to calculate the hydraulic for the grid system for sprinkler system ?
Ok I’m alittle confused with the pipe schedule for the preaction systemsnext to the wet system on that header. Why is it a 2 inch valve them right on top of the valve there a concentric reducer/increaser and the pipe size goes up then ties in to what looks like 4” along with another system? I’ve been in the sprinkler fitters union for 15 years running a service van for the last 10 and I’ve never seen that before.
Because its just meant to show a bunch of different risers for learning components essentially. I wanna say that header wasnt even flowing
Typical fitter, what local?
thanks for this video. this video is very helpful. .. can ask a question?. the remote area is the basis to size the pipe riser? or the whole number of sprinkler of the building by hydraulic calculation?
It can be used to size the pipe riser if you are starting a new system in a new building on a new building site. But most times, in my experience anyways, youll be starting from am existing riser. What the remote area does is determine, if in the worst case scenario, that the system that you have designed will function properly upon activation. It will aid you in sizing pipe or figuring out where you have to make changes as well
thank you for your comment.
can ask something again? how to calculate the area be used in most remote area ? thanks
Dude thank you so much for recording and posting these videos. We don't really have a training program at our company and these videos have been extremely helpful. I actually understand this remote area stuff now so that's cool. Wish there was more!
but how do you transfer that area to autosprink?? because when you place a remote area in AutoSprink it defines the shape and you can't change it....
You're using the wrong remote area tool then. Use the boundary.
Where is this class located at??
Its more of a work training program thats company funded. So youd have to work for the company to go. Personally im newer to the industry as well so i should hope to be adding more videos as i go
Oh man lucky you! Well hope to see more videos!
thanks a ton by the way how to decide most demanding area
Thats either going to be the furthest(or technically most remote) area away from the riser. But it can also be the most hydraulically demanding area, like an area thats a higher hazard or an area using extended coverage sprinkler heads
is this like a college class??? i've seen your other videos and these are really well explained!!
its part of an internal training program for new designers
if you have any more videos like this, or like the one explaining remote areas, please upload them!!! xD
If you go to my page ive got 2 videos on remote areas
thank you!! i've watched them all!!
Excellent!
thank you for this video
why do we need to know first the remote are?
doing hydraulic calculations helps us determine whether or not the system thats been designed for a given structure will work properly in the event of a fire. so we calculate the most remote or the most demanding area of that system, because if that area works then the rest of the system should work
Sir Nick i hope you will make another video on how to design fire pumps . thann you again for this educational video
fire pumps is probably the next most likely video
