NFPA 13d
NFPA 13d
(OP)
Hello all. New guy at this so please be kind. Looking at doing a 13d system for a house. Trying to figure out how calf the system with a home tank. I’m looking a flowing 2 sprinklers at the rates GPM needed. I also have a flow test. But do I use the flow test and the pump together? Or do I start calcs at the tank. I’m also trying to figure out what pressure and GPM for the tank system. Like I said I am new at the pump and tank scene. Any help would be greatly appreciated.

Just plug that pump curve into any computer calc system for fire sprinkler systems and you will be good.
Otherwise just look at your pump data there. Pick the flow that is greater than your demand. Then use the corresponding pressure. That is an over-simplified way of doing it.

You will need the 350 gallon tank. For the computer calcs, just use the pressure at 0 flow for static and the pressure at 40 gpm for your residual pressures.
