Hello all,

I want to calculate my water supply for the fire protection system of an acetylene plant using the NFPA 13 "Standard for the Installation of Sprinkler Systems". I am aware that my occupancy is Extra hazard group one and my demand for sprinklers is 750 GPM (minimun demand using Density/Area Curves). Also regarding the NFPA 51A, I will need hose cabinets.

Now my question is how can I get the water supply, I asume that I have to calculate sprinklers demand + hoses demand, but in that case what is my hoses demand?

thanks in advance
