Is the design criteria for the fire sprinkler system wrong?
Sounds simple enough and, for the most part, it would have been except for one thing. The design criteria for the fire sprinkler system was wrong. I glanced at the name of the project on the title sheet but moved quickly into the guts of the drawings in order to get the design started.
Which is the first formula for sprinkler design?
The first formula of sprinkler design is: 1. ( d) x (A) = Q m Where: d = density (gpm/ft 2 ). (remote area) and/or the assigned area of an individual sprinkler (ft 2 ). Q m = minimum gpm required (gpm). Once you solve for Q m we can now solve for pressure (P). This is its influence on design. The second formula of sprinkler design is: 2. Q m = K √P
