Dredge Jet Nozzles Design


Suction dredge nozzle-intake vs jet vs supply size

For the nozzle I have a 45 degree 2" EMT tube. From what I've read, the jet should be roughly 1/4 of the 2" intake and the jet should be short. What are your thoughts on the jet size with the pump I bought? Also, I'm wondering does the size of the supply matter? I was planning on using 1" EMT to the jet and a 1" supply hose from the pump.

The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. Therefore they do not work very well when working in shallow water.
