What is the maximum distance between sprinklers?
What is the maximum distance between sprinklers?
15 feet
The maximum spacing between two sprinklers is determined by the rating on the sprinkler head (usually 15 feet, but there are other spacing distances, depending on the manufacturer). The minimum spacing between two sprinklers is 6 feet.
How do you calculate the flow rate of a commercial fire sprinkler system?
If, for instance, you have a fire sprinkler with a discharge coefficient of 6.2: 3.87 x 6.2 = 24 gallons per minute. Multiply this individual flow rate by the total number of sprinklers. If your system has, for instance, 15 sprinklers: 24 x 15 = 360 gallons per minute.
What is design density of sprinklers?
The maximum area of coverage per sprinkler head depends on hazard classification and sprinkler mounting orientation (i.e. sidewall or overhead); Design density is the water discharge required in litres per minute over the assumed area of maximum operation.
What is K-factor in sprinkler design?
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2. 0) permit much more water to flow through.
What is sprinkler density?
Density in sprinkler design refers. to the amount of water per square. foot (square meter) that the system. is intended to deliver each minute.
What are the components of a fire sprinkler system?
Automatic Fire Sprinkler Systems – Principle of Operation. Components of an automatic fire sprinkler system. Typically, a Fire Sprinkler Systems are made up from a series of components including; Stop Valve, Alarm Valve, Fire Sprinkler (head), Alarm Test Valve and Motorised Alarm Bell (Gong).
What is the flow rate of a fire sprinkler head?
A typical sprinkler head for commercial use disperses about 20-40 gallons of water per minute. Suppression systems can release a higher rate of flow at 100 gallons per minute. Compare that to the stream of water from a fire hose which can disperse 250 gallons of water per minute.
What is a hydraulic sprinkler system?
hydraulically designed (sprinkler) system. A sprinkler system in which the pipe sizes are calculated on the basis of the pressure loss to provide a prescribed number of gallons of water per square foot (liters per minute per square meter) of floor area, or flow per sprinkler, with a reasonable degree of uniformity over the area.
What is a fire sprinkler designer?
As a fire sprinkler designer, you create fire sprinkler layouts that offer structural compliance and maximum efficiency while meeting legal and industry standards. Your job duties include reading blueprints, drawing floor plans with CAD software, and providing field support as needed.
