There are many variables.
The sprinkler heads come in different sizes.
Rate of flow will be determined by the head-size, the frictional losses in the supply pipework, and the head of water available.
In a single building example, sprinkler heads of exactly the same type, and fed by exactly the same bore pipework, on three different floors will give three different flow rates.
Simple answer? "It varies"
What else can I help you with?
How many gallons of water does a sprinkler use per minute?
almost 400 GPM
How is a fire sprinkler is rated by capacity in gpm or what?
Fire sprinklers are rated by gpm per square foot, plus the temperature at which they are triggered, plus the diameter of the spray (angle of the cone), among other things.
What is an average commercial sprinkler density in GPM per Sq Ft?
The average commercial sprinkler density typically ranges from 0.1 to 0.3 gallons per minute (GPM) per square foot, depending on the type of occupancy and the fire hazard classification. For instance, light hazard areas may require lower densities, while higher hazard areas may necessitate higher densities. It's essential to consult local fire codes and standards, such as NFPA 13, for specific requirements related to sprinkler system design.
How much does it cost to run a sprinkler?
$3.15 per/hour I just did calculation based on: -- City water price of 0.015 cents per gallon of water (water & sewer) -- A GPM rating of 3.5 gallons per minute on the single sprinkler --TOTAL it costs me $3.15 per hour to run a single standard hose-type sprinkler **note: there is a large variation of in garden sprinklers. Some have GPM of 0.5 all the way up to 8. Average sprinklers run 3-4 GPM. I split the difference of the average.
3 WHAT is the Minimum Density for Automatic-Sprinkler Piping Design in light hazard occupancy?
0.10 gpm over 3000 square foot area.
What is the critical velocity of 2.5 inch fire hose?
300 GPM
What is the friction loss in 100feet of 5 inch fire hose?
It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire
What is the turnover rate of a 3500 gallon commercial spa that has a flow rate of 150 gpm?
150
How do you measure gpm on a 2.5 in fire hose without a nozzle?
With a bucket and a stop watch.
How do you calculate gpm?
The easiest way would be to capture the sprinkler water and fill a 5gallon bucket and time your self. When the buckets full then divide the time it took by 5 and you have your GPM.
How many sprinklers can you run on one valve if your sprinklers have a seventeen ft spray radius?
The number of sprinklers you can run on one valve depends on the valve's flow rate and the water pressure available. For sprinklers with a 17 ft spray radius, each sprinkler typically requires around 1.5 to 2.5 gallons per minute (GPM) at optimal pressure. To determine the total number of sprinklers, divide the valve's flow rate (in GPM) by the flow rate required by each sprinkler. It's essential to consider the overall system design and pressure losses as well.
How many gallons per minute does a fire hydrant have?
There is no specific answer. It depends on the water system and the PSI generated. In general the GPM can range from 600GPM to 200GPM and could certainly be lower. Some municipalities color code the hydrants accourding to the GPM produced. This is a terrible answer to a good question but it just depends.
