Fire Sprinkler Capacity

Fire sprinkler standpipe systems.

Fire sprinkler capacity.

As the maximum spacing between sprinklers increases so does the maximum allowable distance from walls. 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. Although historically only used in factories and large commercial buildings systems for homes and small buildings are now available at a cost effective price. In buildings protected by properly designed and maintained fire sprinklers over 99.

Record this number in the gpm box. 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. The sprinkler s maximum distance from walls correlates with these spacing requirements. Next locate your system s static pressure and move down that column and find the system s working pressure.

Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year. 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. 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. 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.
