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"

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.
What is the flow in gallons per minute of a sprinkler with a K Factor of 5.6 and a flowing pressure of 29 psi?
To calculate the flow in gallons per minute (GPM) of a sprinkler with a K Factor of 5.6 and a flowing pressure of 29 psi, you can use the formula: [ \text{GPM} = K \times \sqrt{P} ] Substituting the values: [ \text{GPM} = 5.6 \times \sqrt{29} \approx 5.6 \times 5.385 = 30.1 ] Thus, the flow is approximately 30.1 GPM.
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.
How many sprinkler heads can you run with a 1hp pump?
The number of sprinkler heads that a 1 HP pump can support depends on several factors, including the flow rate of the pump, the pressure requirements of the sprinkler heads, and the layout of the irrigation system. Generally, a 1 HP pump can deliver around 10 to 15 gallons per minute (GPM). If each sprinkler head requires about 2 GPM, you could potentially run 5 to 7 heads effectively, but this can vary based on system design and head specifications. Always consult the manufacturer's guidelines and consider the entire system's dynamics for accurate planning.
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.
