Fire Sprinkler Capacity

Fire sprinkler standpipe systems.

Fire sprinkler capacity. Record it in the psi box. 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. Record this number in the gpm box. The sprinkler s maximum distance from walls correlates with these spacing requirements.

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. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. 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. In buildings protected by properly designed and maintained fire sprinklers over 99. 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.
