Wirtz pumps are really clever

This spiral pump uses air lock to push water to great hights.
Here’s Johnathan Deane’s paper on the subject: https://openresearch.surrey.ac.uk/esploro/outputs/journalArticle/A-hydrostatic-model-of-the-Wirtz/99515507702346

If you’re getting deja vu it’s because when I first uploaded this, the audio was borked for anyone listening in mono. Thanks Premiere Pro! It’s fixed in this version! Thanks for your patience.

🎵 Deja Vu! I’ve been in this place before (higher on the street) and I know it’s my time to go! 🎵🎶
I paused the video got busy with some work when i went to play it again poof gone… thanks for the reupload!!!
Switch to resolve already
Also there was an extremely audible fart at 7:37 which has been removed
It went away the moment you said ”I’ve never made a misstake in a video before”
I just love the fact he managed to get an entirely nature powered bog garden from a pump
I wonder what came first – his desire for a bog garden, or his desire for an excuse to build a self-powered Wirtz pump?
Agreed. Great taste, terrific idea and an execution to match both. I’m green with envy, tbh! 😅
What is a bog garden?
Edit: I just looked it up, it’s a mosquito paradise…
@Pronto a proper bog garden shouldn’t have still water. and if it does you can just place some fish there to eat the larvae.
@Danilo Oliveira Also frogs
The fact that guy has it pumping 8 metres up his garden with no power other than the stream is incredible. I love this stuff.
The other main option is a hydraulic ram pump, Practical Engineering has a good video on that
Decently mobile driver with some nice big paddles helping the spin.
Still, it’s learnt been running a while given the amount of miss, etc on the wheel
Maybe much quieter than ram pump 🤔
It is a brilliant pump.
The only 2 problems are input fouling (which exists with any pump)
And the rotary fluid coupling
@gregw1076 I think it would have to be somewhere underground to get the potential it needs, and then maybe somewhere to remove the “wasted” water
It’s worth mentioning with air locking that air is more compressible than water, which means for the air to exert as much force on the next stage of water, the water behind it has to be exerting more pressure on the air than it would need to on just more water.
In your three-stage demonstration, the water and air have time to find their natural equilibrium such that the pressure being exerted between each section of air and water equalises with the outside air. So the air inside is uncompressed, and when the water is forced to move again, the air will begin compression before it starts exerting enough force to start moving the next section of water at the same rate as the water behind it. It’s kinda like pushing a block of wood with another block of wood via a spring… but also up and over a hill.
perfect explanation
Yeah, that’s part of the principle behind a hammer pump. The compressible air acts as a spring.
It’s proof of the kind of great man you are when you’re able to admit the one and only mistake you’ve ever made in your life. Props to you! Cheers.
I hope that when I make my first mistake, I too will have the courage to own up to it.
the pause after he confessed was gold aswell.
actually most of the science channels do this. That’s a way how you can see if a source is legit or bs.
He’s not that great, this is clearly a Matt Parker video with a some cameos by Steve Mould but Matt is not mentioned anywhere in the title.
@Electric paisyit’s a joke that it’s the only mistake he’s ever made.
Could it be made so instead of the coils spiralling inwards towards the centre, they helix along the z axis making all the coils exactly the same circumference? Would it make any difference?
This pump reminds me of a water ram, which has always seemed to me like (almost) getting something for nothing.
obviously nothing is free, it uses flowing water which is gravitational kinetic energy, but on the human scale it is functionally free since it is energy we would really never be using otherwise nor does it have any appreciable effect on the system or environment (like a dam). its about as “free” as solar and geothermal and such.
@daktah Duh.
@Dr Joey then why even bother making your original comment 🙄
@daktah Why bother re-stating, in many more words, the point I’d already made?
Yeah, they both seem like perpetual motion until you look really closely.
Love seeing Matt Parker doing Matt Parker things and even cooler you both found reason to visit this amazing pump! It’s always amazing to see older tech with such a novel approach to solving a problem.
but what if… it’s not Matt Parker
What’s really cool is that you don’t need any back flow prevention valves with these. The air lock stops the reverse flow of water if it stops. I work in irrigation sales and engineering and this stuff always amazes me. The physics of any pump system and how to create pressure is just cool stuff.
I had one of these. Back flow valve actually helped increasing the head, pretty much double.
“the 2d fluid mechanisms explanations channel” is my favorite channel and i never miss an upload
the 100% that’s what water looks like channel
I hear he has a huge number of fans in Flatland.
I also enjoy your other non fluid videos Steve
