about designing of a fire sprinkler system 3

See the NFPA forum and download some of the free NFPA manuals and codes.


NFPA 13 looks like what you need.

Any sort of pipe network analysis can be quite complex depending on pressures and flows.

LittleInch... great link.

BTW, try not to be under one of those fire-suppression sprinklers when they ever go off. I experienced that once when we were installing a large commercial oven in a what had been a grocery warehouse and the building owner had forgotten to change out the sprinkler heads for high-temp units. We had just fired-up this large (something like 80 foot long, 12 foot wide) tunnel oven for the first time and about 4 hours into the test and set-up procedure the sprinkler head over the discharge end of the oven popped. Note that this was in East Hartford, CN and it was in the winter time, so that water was very cold. Anyway, it's amazing how much water can come out of just ONE sprinkler head. Except for when I've been in a pool, I don't think I've ever been wetter in my life ;-)

If you have to ask how to design a fire sprinkler system, it is suggested that you have a major learning task ahead of you in the design of something that is safeguarding people's lives.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

I think I have seen the topic come up in a number of states as to whether the design of fire sprinkler systems constituted professional engineering and required licensing. Regardless, check in your locality and see if there are specific requirements as to who designs the system. In additions to Artisi's point above.

You will not find a sprinkler system design in the form of a grid. There is no such animal except in the figment of the imagination.
