2014-2-28 Hi Tazla, The orifice size sets the pressure and flow in the jet. So a 1/16 gap is the same area of a 1" orifice on a 4" jet (does not stay the same on other sizes because circumference vs area changes) and would provide the same PSI at a certain flow as a log jet. So engine rpm would be the same for both jets, but increased suction is provided.

The infinity jet produced the most vacuum, the tri-jet was 2nd, the suction nozzle was 3rd, the straight jet came in last in performance. There are some strange dynamics going on inside the various jets. If one were to make each jet out of clear plastic, then he could study the fluid dynamics going on inside each jet.

The rock person should be moving the very next rock that is in the nozzle’s way.. Silt is usually released when a rock is moved out of the streambed. So an R/P must be careful to not “cloud-out” the hole (loss of visibility). This can be avoided by concentrating on (a) moving those rocks that are near to where the N/O is working (this is the first priority), or (b) moving those rocks ...

A suction nozzle works in a similar fashion to a power jet except instead of being attached directly to the header box the nozzle is attached at the far end of the material hose. A vacuum is created which sucks up water and gravel but the material is pushed through the hose instead of being sucked through the hose, as in the case of the power jet.
