Fire Sprinkler Capacity

Using the system design capacity chart on this page locate the three numbers you just recorded to determine the sprinkler system design capacity in gallons per minute gpm.

Fire sprinkler capacity.

Fire sprinkler standpipe systems. A fire sprinkler system is an active fire protection method consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system onto which fire sprinklers are connected. A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected such as when a predetermined temperature has been exceeded. Next locate your system s static pressure and move down that column and find the system s working pressure.

Designers rely on mathematical analysis of pipes capacity to distribute water to fire sprinkler heads. The first step is to calculate the minimum flow which will be required at the most remote sprinkler which in this case is at node 130 this is a two step process as will need to calculate the minimum flow required to satisfy the 7 50 mm min design density and then find the flow rate from the sprinkler given the sprinklers minimum pressure requirement whichever is the greater flow will. I created this when looking at whether i break the 5 gallon volume threshold for portions of wet sprinkler systems bottom legs of standpipes or. Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year.

Select the type of pipe used and enter the approximate length of pipe for each pipe size in the system or portion of a system you re evaluating. In buildings protected by properly designed and maintained fire sprinklers over 99. Record this number in the gpm box. As the maximum spacing between sprinklers increases so does the maximum allowable distance from walls.
