moving laminar bells
Here's one I sent to liteglow via youtube, but I thought I'd post it here, too. I've been playing with bells, which is when laminar jets collide creating a bell-shape of water. By changing flow and pressure you can make them walk up and down each other, the bell moving from side to side. what I really want to do is create a computer controlled program where the bell and arcs of water quickly run along each other making a single arc as in the first section of the video, or two dynamic arcs in the second.

Re: moving laminar bells
I will try to make 2 of my laminar to hit each other when hey jump into my funtain
But I dont have pump that can be controlled on the output....
they run wth a constant ON flow all the time..

Re: moving laminar bells
That's pretty cool! Is that video yours? How do you plan on controlling the pump output? That's some pretty good output. How far does it jump before it starts to break up?
Re: moving laminar bells
Yeah, that's a video I took after I assembled the nozzles in the studio I'm working from. How much distance the flow will go and still be laminar depends on how tight the arc is. If I aim the water almost straight upwards and the arc is really tight, the water falls apart within four feet. If I angle the nozzle so the water has a low, shallow arc, the jet is still laminar 12 feet away.

Re: moving laminar bells
It appear that you are using the 4" pipe, is that right? If that is the case then what is your secret? I worked with a 4" (my current design is 8") and I couldn't get any better results then a 3' x 3' arc, and that's probably being generous. What's the layout inside your nozzle?
You mentioned a studio?

It's a simplified version of the Ayer nozzle from the 70's.
If you can handle the droning of an educational video me an' Ben show the assembly in this video around 3:20. The ones making the laminar bell had the rings holding screen in place epoxied since they're permanent nozzles.

Re: moving laminar bells
Really funny, and seems to be working for a simple installation.
What is your plan to do with it?

Re: moving laminar bells
We're trying to par down the nozzle size because I want a laminar shower head...
Aside from that I want to make a portable display where I can hook the pump and the control circuit into a wall jack, I'm not sure how possible that would be, but my background is in traveling educational shows, and the laminar fountains are such a great demonstration of intro. physics. I'm deciding what control system I want right now, and hunting around for cheap pumps that have the capacity needed.

Re: moving laminar bells
I'm not sure what you output is, but I'm guessing that you are probably needing about a 10-20 GPM fountain pump. I can't vouch for the reliability of these pumps, but harbor freight has some cheep stuff.

Re: moving laminar bells
I just ordered a solar pump system from them this past week! They do a lot of general hardware supply around the country, according to a guy I know who does farm store management. I'm eager to see how well the pump kit I'm getting works, as I was surprised by how cheap it was. It's not possible to make a laminar jet with a really low flow rate like the solar kits put out, because you need a lot of flow at low pressure, but I want to see if "you get what you pay for" applies as strongly to pumps as it does to, say, mattresses, or concert tickets.

Re: moving laminar bells
I hope it works, because I bought 2 80 gpm pumps from them last year, that I still haven't hooked up. Soon, so very soon.....
Re: moving laminar bells
i dont know about GHP..
But I try 2400L\hr and it was to small..
Next to try is a 5000-6000Ltr\hr pump..

One gallon(US liq.)) = 3.785 liter
80 GPM is a 18000 liter per hour, this i ok for 3 or 4 nozzles, with only one you need to power down to 30%, that is no good for the flow. I have one with 12000 LPH, was very hard to control, too much power. the cheap one i use is a 5000 LPH and is ok for my Nozzle but has not a permanently pressure.
A 5000 - 6000 liter per hour is ok. I plan to buy a professional Pump from oase, they have a very good permanently pressure. The Neptun 5000. i found one used in my country in a auction. Around 200$, new is 350$.
The blue lever is the pressure controller.

Re: moving laminar bells
thanx for sharing the info
I think I will use 4 pumps, one for each laminar jet !
My ew pump will arrive soon, then I will test and upload some new videos
The pump I buy is a "professional" pump, that is ment to be used outside on ponds ++
The FLOW4500 did cost me 160$ ..
So you do the math 160$ x 4 =
haha
