The area of the 1.0 jet was 0.785 sq..
nozzles with high velocity. The nozzles are fitted to the dredge head with banjo joints so that the angle of the nozzles can be changed for maximum concentration slurry. The high-pressurized water jet from the nozzles impinges on the seabed. By this process heavy mineral sand is loosened and it forms sand-water slurry inside
In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredge-hose. I repeated the test 5 or 6 times and the results were always the same. The suction nozzle drew 75 GPM and the tri-jet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...
