Ok, now I'm thinking 6 3/16th jets might be on the perfect ragged edge with just a bit of fudge room for my mini pump running a 2.5" dredge. Enough flow, and vacuum drag to pull/push to small rocks and silt off the bottom and put gold in the sluice..........?? My dredge nozzle will either have a 2" restrictor ring or more likely a pin through the middle to keep the big stuff out.
Now I need to start thinking about sluice size and setup (hint 9"wide x ? )with gold hog mats that I still need to order.
To many jets... If you figure that a P100 uses a 5/8 opening and you are running a lot less than that I would think 4 - 3/16" should be plenty because you want the most pressure that your pump can handle going through the jets. And honestly, going more than 4 is just making more welds on a pipe that will need to be re-straightened after anyway. To me - more than 4 looks like more work and overkill that's not needed. I would think 3 - ¼" id square tubing jets would be easier to use
