My first try at a laminar flow nozzle
I've been lurking on this forum for several years, intending to try my hand at a laminar flow nozzle when time premitted. Well, recently time did permit, so I've built my first nozzle.
I used 4" diameter PVC, two feet long (that was already cut at Lowe's), and inside I have the fairly usual scrub pads and bundle of drinking straws. My outlet is just a 1/2" hole bored in a plastic test plug with a spade bit and smoothed a little with some steel wool - certainly needs improvement. My inlet is straight into the back, not a tangential one, so that's clearly another thing to improve. I simply hooked it up to a 1/2" garden hose to see what might happen and the video at the link below shows the result. I was pleasantly surprised.
I can make a tangential setup pretty easily, I think, but I'm wondering if anyone can help me get a proper "standard brass outlet" that so many of you use.
My intent is first to plumb it to my pool pump (may require a damper to smooth the flow) and then to add light. A cutter is not high on my list right now.
I'd welcome comments, suggestions, etc.
