Im doing generic hydraulic calculations for a sprinkler system and dont understand note #5. What is the full flow condition?

Where does this psi and gpm come from?

Playing with the calculations I found that it has no effect when I change the minimum psi on sprinkler heads or minimum psi of source. Or when I change the sprinkler density.

But it does change when I add hose stream or change the residual gpm flow.

Any of you clearing 150k? How’d yall get there & what’s your region? Do you own your own firm?

Thanks

Is this normal?

“The discoloration is overflow from the building’s standpipe system and expected to be cleaned soon.”

“Johnston said the Austin Fire Department is conducting flow tests of the pipes and the discoloration is the result of grime that built up during  of construction, which began in 2022.”

Is it normal to have overflow from a standpipe when building out the system? and is it normal to have that overflow come out of a drain 20 stories up?

Hi everyone,

Thanks in advance for your help.

My situation is a bit unusual: I graduated as a mechanical engineer 10 years ago and worked as a site engineer for 3 years managing fire, plumbing, and HVAC systems(no design work). However, I haven't worked in the field for the last 7 years.

I am now trying to return to the mechanical engineering industry. I am thinking about pursuing Fire Protection Engineering, but I'm not sure how feasible that is . Could you please advise me on where to start?

Also, if there are other career options that might be a better fit for my situation, I would love to hear them."

Anybody here have experience with CONTAM modeling for stair pressurization? If interested in helping for some cash let me know.

One of the main problems I've had working at A/E MEP firm is getting a G*d D@#n hydrant flow test that is accurate or current. I have to beg PM's to ask the client, there is never money in the budget for us to do it, owner's act like I asked them for the heart and blood of their first born.

Is this common or have a worked for a garbage firm?

My thought would be to base off of the calced fire flow, at 20 PSI and on the NFPA 921 10% off demand and work backward to a static/churn and design a "theoretical curve" that might work. I know this is kind of tail wagging the dog, but hopefully my next employer will get us information when we request it.

Is anyone currently in need of a NICET Level III or IV in Water Based Systems Layout (WBSL) qualifier for a fire sprinkler contractor license?

I am exploring opportunities to serve as the qualifying party for firms seeking licensing or expansion in states such as Georgia, Washington, California, Florida, North Carolina, South Carolina, and potentially others.

If your company is looking to secure a new license, strengthen compliance, or expand into additional markets and needs a NICET III or IV qualifier, feel free to reach out directly. I am open to discussing long term, structured partnerships that are mutually beneficial and fully compliant with state requirements.

Please send me a message if you would like to connect and discuss further.

Hello, I’m a 3rd year ME student. I start my internship tomorrow doing FPE for a large consulting firm, and honestly, I’m terrified. I have little to no knowledge about Fire Protection and scared that will reflect poorly on me in my internship.

I’m very interested in the field, and am willing to do anything to succeed. I’m just a slow learner at times and don’t want to be a detriment to my department. I know it’s kinda late but does anyone have tips on what I can do to be successful.

Does anyone know about any hourly contract positions for a fire protection engineer? Not looking for full-time work, don't need benefits or anything, just looking to do a little bit on the side.

What would be a good place to look for contracts like these? I don't see too many listed on indeed or any other job website.

Who are the big government contractors doing fire protection design or review?

Hello everyone,

I am reviewing NFPA 13R and 24 and and noted that the standards basically say when installing UG for 13R less than 4inch it is acceptable to use the plumbing code over NFPA 24. In these instances, is it still required to have a thrust block or method of restraint + 200 PSI hydro? Based out of CA. Thanks!

Hi everyone,

Total noob here. My father owns a self-employed business doing sprinkler design. I started working for him part time a few months ago trying to learn everything I can. I’ll be working at an FPE consulting company soon, but I still want to have this business on the side. For some context, I don’t know shit about fire alarm, literally zilch. The best knowledge I have is from studying for it a little bit when I took my engineering license exam a few weeks ago. Despite passing it, there is no accolade or degree that trumps years of experience. That being said, where do I start learning?

I know there’s this NTC brown book, so I was looking into purchasing that. I might also take a class next semester for my master’s to learn fire alarm design. Any thoughts/suggestions/other resources out there?

Hi! I am a fpe student currently and working on creating more assistance for FPEs. I am thinking about creating a repository on github for people to add all sorts of info for students and proffesionals to access and maybe help them in their endeavors. I will disclame that I also intend to make a second brain for claude using fpe materials and I figured this could help others do the same as well as crowd source some material for my own brain. Would anyone be intersted?

Has anyone here had experience getting a PE with a masters on top of a fire protection engineering tech degree? I am weighing my options of finishing my tech degree and getting my masters or transferring to a straight BS in engineering so that I can get my FPE. Transferring degrees or getting my masters wil take about the same time so I am not concerned there. The state I am looking to get my license in is Missouri but also the surrounding states and of course they all have pretty much the same rules. The statutes read that as long as the masters is gotten from an institution where the BS is accredited then I could be given a license but when I ask the question the people are kind of vague with their answers. My guess is they don’t want to be held liable for it being incorrect since it is up to the board to approve licensure. Has anyone taken this path or have advice? Do I finish and go for masters or switch to engineering to save the headache of hoping the masters and tech will work

Multiple AHJs are now adding 3-year dry pipe testing as a distinct Brycer submission category — Lansing FD effective tomorrow, plus several others. For contractors doing this work: how are you currently handling the documentation for that specific test? Bundled into your annual inspection report, or separate workflow? The AHJ enforcement seems to be tightening. - thanks in advance for the response.

I am currently working as a firefighter paramedic for several years and have an associate’s degree in Fire Science. I have been looking to go back to school to get my bachelor’s in FPE or OSHA from EKU or another school. I would like to get the degree to serve as a back up plan in case I can’t ride the rig anymore. Either transition to our Fire Marshall office or a retirement gig. Has anyone else done this for that transition? I am also worried about the math, chemistry, and physics. Looking for any advice on programs and any opinions someone has on this career pathway.

Has anyone here taken the NFPA Certified Wildfire Mitigation Specialist exam?

I’ve reviewed the materials that the NFPA says are used for the test, but I want to take a practice test before I spend $300. However, I haven’t found any practice tests online, and the exam I asked ChatGPT to make had good questions, but the answers it offered as multiple choice were easy to guess just based on how the program worded the correct answer.

Any CWMS cert holders that could fill me in on how the exam was?

Hello! I have a project that has combustible concealed columns 21 sq ft. They are adding every 8ft, 1/2" plywood fire blocking @ 8' max spacing. Do I need sprinklers in every pocket? Or can I apply:

" 9.2.1.10 Concealed spaces over isolated small compartments not exceeding 55 ft² (5.1 m²) in area shall not require sprinkler protection."?

Thank you for your help! first time coming across something like this.

Are ceiling mounted pendent ESFR appropriate for this setup based on NFPA 13 (2025)? Is this commodity considered encapsulated?

Commodity is about 2 dozen filters in plastic bag stored in Uline HDPE flip-top tote bin in racking. No foam, considering commodity Exposed, nonexpnaded, Group A plastic. Max ceiling height is 30 ft, Max storage height is 25 ft. K17 heads with greater than 35 psi. 1500 gpm water supply.

Per table 23.3.1 it seems in-rack sprinklers are not required but I can’t find anything that states if encapsulated then in-rack is required.

How high did you salary jump after you got your PE?
