First Attempt at a Nozzle

After much research I have built my first functioning laminar flow nozzle. My nozzle is very simple. I made it out of 3" PVC. I used a removable clean-out as the base, connected to a T, connected to a foot of 3" pipe. The nozzle is simply a 3" test cap with about a 1/4" hole drilled in the center. I used 150 and 600 grit sandpaper to smooth out the nozzle hole and add the taper on the outside. Water enters the nozzle through the T fitting. I used a 1.5" coupler which is threaded and screwed in a 1/2" hose barb connector. Inside I started with aluminum screen held in place by a plastic ring cut from a 4" test cap, followed by 3 scouring pads, followed by drinking straws and finally another piece of screen again held in place by a plastic ring. There is about 2" of empty space between the top screen and the nozzle. The nozzle is connected a 17 watt pond pump and I can get about a 10" tall and 1.5 foot wide arc.

My next nozzle will use wider pipe, a better nozzle, a more powerful pump and a low pass filter. I also plan to add RGB lighting.

Feel free to ask questions.
