I don't know Stook, like I said, the MEP gave me the information for the sprinkler. Should I "stop the presses" and find out? My scope is site engineering, but I do want to make sure the building is covered in the event of a fire. Did you work for the AFD in 1990? You don't really notice...

According to the MEP, "Fire Sprinkler System: Worst-case design flow demand estimate: 2214.9 gpm @ 77.17 psi (for existing system Zone 1 per hydraulic information placard)" I do not know of any flammable liquids or rolled paper inventory.

Not that it matters to anyone else but me, but anyway.... I just talked to the reviewer for the Fire Department and she said that they do not care what the fire sprinkler demand is, they just want to know their line has enough capacity for their fire engines. I told her they will both be...

Thanks Stookey, fyi - The sprinkler demand is over 2,200 gpm at 77 psi for the old paper press.

Thanks stookey, but that is the reduction in fire flow for sprinklered buildings. I am looking for something in print to tell me the fire flow and sprinkler flow are independent and not concurrent uses. The exception to B105.2 would lead me to believe that in order to reduce the fire flow...

All, Thats a great thread and it provides a lot of information that amy seem counter intuitive to people like my boss. If the fire flow and the sprinkler demand are independent, what code from IFC or NFPA can I quote to show my boss the hydrant and sprinkler demands are not additive? fyi -...

I am modelling a private line with two hydrants and a fire sprinkler system for a newspaper press building here in Texas. I am having trouble reaching the pressure required for the sprinkler system and the MEP for the project (located in Colorado) told me the demands for the sprinkler and the...

EPANET 2 set up question. I have input my demands, lines, nodes, losses, elevations for my system. I have converted the fire hydrant flow test to a reservoir with additional elevation. The line I am connecting to in the R.O.W. has two fire hydrants that I need to find out Flows, Pressures and...

I interview the same person twice because sometimes the applicant is on their best behavior kind of like a "first date." A lot of time, I like to meet them at Starbucks and talk non-work related so I know where they are coming from. i don't want anyone in my office that talks like a sailor or...

Has anyone else had a chance to outsource the compilation of construction plans? All of the graduates I interview are asking for $50,000 plus benefits and at the same time I receive a steady stream of emails asking $3 per sheet. I don't mind paying technicians/engineers overtime but I can't...

I think a 3 snuck into your depth of flow calculation. How about converting flows and slopes to depths of flows.

I see on past discussions taht there is a spreadsheet floating around with an iterative equation for depth of flow in a partially full pipe. Here in Austin we are required to design to 85% full or less for the 100 year. Being from Houston, we always assumed full flow and designed for 2 year...
