    Depends on the nozzle and pressure.

    All the major sprinkler manufactures have charts that show how many GPM each nozzle outputs at certian pressures.

    Take a look at their websites, or just tell us what heads your referring to.

    Best way to find out (but not the most accurate) is take the hose you are using and open the valve wide open. Take the hose (not while it is connected to the sprinkler) and put it in a 5 gallon bucket for one minute. Measure the amount of water in the bucket. Thats the max amount that hose will produce. You can repeat the test with the sprinkler attached to the hose if you don't mind getting wet. If the bucket fills before one minute change the time to 30 sec. and double the amount of water for the gallons per minute total.
