Center pivot and lateral move irrigation systems consist of a continously moving lateral
with sprinklers mounted at an equal or variable spacing. The discharge rate on a center
pivot increases linearly from the pivot, and can be as high as 1.5 gallons per minute (gpm)
per foot of lateral near the outer end of a 1/4 mile lateral. Due to the high discharge rate,
and nozzle size limitations, which typically limit nozzle spacings to 5 to 15 feet,
uniformity of application is usually quite high
