Frangible
That would depend upon what type of sprinkler it is, how far apart they are, what type of occupancy, what is the purpose of the wall and the material of the wall, among other things. For example, some walls do not need any sprinklers at all.
25-150 gallons per minute is standard depending on the type of sprinkler head. Residential sprinklers will be closer to 25. That flow is for a SINGLE sprinkler head. Typically the fire will be extinguished by just activating one sprinkler head.
Upright heads
Wet pipe sprinkler
You'll need some rock bed, a good amount of fertilizer and possibly some sprinkler piping if you have a sprinkler system below ground.
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"
To avoid problems of freezing water and broken pipes, a "dry sprinkler" system can be installed. The sprinkler heads can be sealed shut with temperature-sensitive valves, as in most wet systems, but the pipes are put under air pressure instead of water pressure, until one of the heads is activated by a fire. Water rushes into the system and sprays out of the open sprinkler head(s) within seconds, if all goes according to plan.
A drip or a sprinkler or overhead irrigator is used

An irrigation company provides such services as sprinkler systems, pipelines, rivers and streams. One would need a company like this when water is needed.
