The max height and distance of the laminar stream I was able to achieve with these jets, was about 6'high and 8'out, You can figure the velocity of the stream by simple trajectory physics. The pumps I was using were just simple fountain pumps from Home Depot around 600GPH
I do have one additional thought, perhaps you've already experimented with it so I'll ask you in an effort to save me some aggravation. Is it possible to shape the external flow? All I've ever seen so far are round, cylindrical flows; do you think that if the tube were square as well as the nozzle that the flow (rod) would come out as a square tube?
I, too, am impressed with your detailed videos. I have been working on my first laminar flow with very eratic results. Each time I turn back to the net and end up on You Tube; this time I found your tutorials and can see precisely what I've been doing wrong in various aspects of the configuration.
Hello Zach. Thank you for a thorough and competent series of videos on the Laminar flow nozzle. I have been working on one and your videos will help me avoid mistakes. I particularly like the cylinder for evening out pressure variations. I wonder if it would work as well with a four inch pipe?
Hello Zach, I saw many you tubes with the same design flaw in which the water exits the straws and returns to a state of confusion in the head space prior to fighting for the nozzle exit. The water is no longer layered. All these units do give the appearance of laminar flow because of the slow feed but in reality the nozzle needs to be the same size as the packed staws or the straws need to be packed in the shape of the nozzle you have created.

What flow rate or outlet velocity did you get through the half inch outlet?

@MalcolmDyer : Yes it does work on smaller pipes,, But the biggest good laminar stream I could achieve with a 4" was around 3/8"

Why not invert the the output valve so sharp edge is last thing water sees?

@evdeals: That is exactly how it works.
