How do you calculate how much water you need for fire fighting?

The basic formula in the schedule is: NFFi= (Ci)(Oi)(X +P)i Where NFFi = needed fire flow (NFF) in gal per min (L/min) Ci = a construction factor that depends on the construction of the structure under consideration Oi = an occupancy factor that depends on the combustibility of the occupancy (X = P)i = an exposure …
