It can vary a huge amount depending on the type and size of the sprinkler, from as little as 1/2 gallon per minute to well over 8 gallons per minute. A reasonable average for the kinds you might purchase in a large discount store would be about three to four gallons per minute.
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.

$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.

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!
It depends on how much water was in it to begin with and how much water is entering per minute.
"The average sprinkler will use in excess of 240 gallons of water per hour" also refer to http://www.libertylake.org/water_conservation.htm for watering guide. As a useful gauge: A garden hose with no nozzle attached, will spew out as much as 350 gallons per hour. So 240 sounds about right for a sprinkler system, keeping in mind that it will vary with your local water pressure and type of sprinkler system that you have. If your system has a damaged sprinkler head, you might as well be running that garden hose full blast. My sprinkler system uses 1,000 gallons in a three hour time cycle. I have six or seven zones. I suspect some of my heads are busted, since that sounds about like "garden hose figures." (333 gallons per hour)
To properly blow out your sprinkler system for winterization, you will need an air compressor with a cubic feet per minute (CFM) rating of at least 80-100. Start by shutting off the water supply to the sprinkler system and opening the drain valves. Connect the air compressor to the sprinkler system using a quick-connect fitting. Gradually increase the air pressure to blow out the water from the pipes and sprinkler heads. Work zone by zone, ensuring all water is expelled. Once completed, disconnect the air compressor and close all drain valves. This will help prevent freezing and damage to your sprinkler system during the winter months.
