The likelihood that a sprinkler could discharge accidentally due to a manufacturing defect is extremely remote. Your home is much more likely to be damaged by leaks from ordinary household plumbing than from a residential sprinkler system. Water damage from a sprinkler system would be more extensive than the damage from the fire itself.

Density/Area method of hydraulically calculating a sprinkler system has served us well for many years, but it is time for it to go. Join us for this webinar to learn the history of the density curve development and why it’s time for a new approach. An automatic sprinkler system is designed to distribute water or foam solution to a specific hazard area. The application rate, commonly referred to as ‘‘ density,’’ is frequently expressed in units of gallons per minute per square foot ( gpm/ ft2) or liters per minute per square meter (Lpm/m2) of area. The worst potential fire situation is generally used to determine the number of sprinkler heads discharging. For the tank above the highest sprinkler P C 30 A > 5 For the tank below the highest sprinkler 30 P C A > 5 = 0.434H A A C proportion of air in the tank P C air pressure carried in the tank in psi H C height of the highest sprinkler above the tank bottom in feet It can be seen that these formulas are based simply on the need to provide a minimum pressure of 5 psi (.03 bar) to the system at the level of the highest sprinkler, and an assumption of 5 psi (.03 bar) atmospheric pressure. hydraulic calculations.
