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.
to spray water; either as a fire extinguisher, or for watering lawns and fields.

Ordinary water is used in most fire sprinkler systems. Most fire sprinkler systems are connected directly to the same water you get from the fire hydrant, which is also often the source for drinking water as well.
The term sprinklers typically refers to devices that discharge water for irrigation or fire control applications. Irrigation sprinkler systems can be either manual or automatic. Three common types of irrigation sprinkler heads are sprays, rotors (impact or gear drive), and multi-stream rotators. Fire sprinkler systems types include wet pipe, dry pipe, deluge, pre-action, foam water, and water spray. Common types of fire sprinkler heads are bulb, upright, pendant and side wall.

An irrigation sprinkler is a device that applies water to plants, mimicking the effect of rain, as it is done in lawn, garden and agricultural irrigation. A fire sprinkler is a device that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been reached.
Maximum drop of the deflector when the concealed sprinkler cover or what they call escutcheons is released, should be at least 1/4" of an inch from the horizontal height of the ceiling to spray the water during sprinkler operation in case of Fire.
A "deluge" system floods the entire system when sensors detect smoke or heat, and the sprinkler heads do not have individual valves, as would be found in most systems.
Over 40 million fire sprinkler heads are fitted each year. A fire sprinkler is a component of a fire sprinkler system that discharges water onto fires in the area once the effects of a fire have been detected, such as excessive increase in temperature.
Depends on the system, and it's design. Most standard sprinkler systems are designed for a 30 gallon per minute rate for each sprinkler head. Standpipes and hose lines have other design criteria, as do deluge systems. They ALL take a LOT of water!
Fire department connections are actually used in fire sprinkler systems.When any fire occurs water is discharged from the sprinkler heads that have fused, and are discharging water to supress and extinguish the fire. The fire department connection is used by the fire department to add to the water supply to the sprinklers and/or charge the interior hydrant connection withn the building (if any).
The sprinkler head design. High velocity heads have longer nozzles with a venturi tube (a type of curved nozzle) which increases the velocity of the water spray. Medium velocity heads are shorter and do not use a venturi.
