Fire Sprinkler System Capacity

The water supply needs to be capable of supplying all sprinklers that operate during a fire and providing water for fire department operations during the fire.

Fire sprinkler system capacity.

1 for situations where the jockey pump serves only above ground piping for fire sprinkler and standpipe systems. 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. 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.

A building s water supply whether it s the municipal waterworks a well or a tank must have enough capacity and pressure to meet the demands of its fire sprinkler system and a pump must often augment pressure. The jockey pump should be sized to provide a flow less than a single fire sprinkler. In buildings protected by properly designed and maintained fire sprinklers over 99. 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.

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. Sprinkler water pressure is essential but how much is enough. Record this number in the gpm box. Fire sprinklers are extensively used worldwide with over 40 million sprinkler heads fitted each year.

Every sprinkler system requires at least one automatic water supply of adequate pressure capacity and reliability. 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.
