A nozzle for a rotary water delivery system comprising at least a pair of nozzle orifices of similar size spaced apart on a face of the nozzle and having a nozzle orifice size to nozzle orifice spacing distance ratio of about 1:2 to about 1: 10, said ratio being sufficient to produce separate nozzle streams which emerge from the nozzle face as separate streams which may join together or commingle only at a distance from said face which does not appreciably increase an overall velocity of a resultant stream or commingled stream or individual streams so that the gallonage per minute delivered by the nozzle can be increased incrementally in multiples without appreciably increasing the distance thrown by the resultant water stream. |
