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.

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.
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 3500 gallon commercial spa that has a flow rate of 150 gpm?
150
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.
Sprinkler coverage area for extra hazard heads?
Extra hazard occupancies require densities of either 0.30 gpm/sq ft or 0.40 gpm/sq ft, for which the maximum head layout is 100 sq ft per NFPA 13. There are some sprinkler heads in the market that allow coverages up to 196 sq ft with a special listing. Tyco EC-25 and EC-17, and Reliable MBEC-14 are some of the heads that can be used with certain restrictions.
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.
