The term waterjet divergency was introduced and defined. Divergency was measured in material (steel) in static regime - piercing - and then compared with jet divergency in free air measured in dynamic regime - cutting. The cutting divergency was measured for two different traverse speeds 2 meters per sec and 10 meters per sec. The experimental results are summarized and discussed. The results of experiments are compared with theoretical value. The influence of the abrasive mass flow rate on the jet divergency is mentioned.
