This is similar to how an electronic boost converter works. The water's inertia is like an inductor, and the output check valve is like a diode. The other check valve is like a switch.

I love how sometimes, the math that is used to describe certain things in classical mechanics is the same math that is used to describe certain things in circuitry. For example, if I remember correctly, the math that is used to describe a spring mass system is extremely similar to the math that is used to describe an RLC circuit. How fun is that?

[@YSPACElabs]

@Ethan Renckly Pretty cool. Like pulse tube cryocoolers have a resonant frequency like an LC circuit. And impedance matching is kind of like a perfectly inelastic collision between two objects.

[@ethanrenckly787]

@@YSPACElabs I only knew about half of those things because of my AP physics teacher in high-school, as well as the engineering classes I took in high-school (Principles Of Engineering and Digital Electronics). I'll try to remember the rest of that stuff for Electrical Engineering and Mechanical Engineering which I will no doubt take in college. So, thanks, I guess.

[@YSPACElabs]

@@ethanrenckly787 The pulse tube cryocooler info was from Hyperspace Pirate, and the impedance matching was from stuff I read online and from my own intuition. It makes sense, so it might be correct.

[@ethanrenckly787]

@@YSPACElabs Hey, to be fair, most of the more random stuff I don't learn in school (which is most of it) I learn by reading online. I also want to mention that most of the math I know beyond pre-calculus was either taught to me by my AP physics teacher or self taught, which means I understand concepts beyond calculus 3 (my favorite math is complex analysis, specifically iterative complex analysis). It's also due to this fact that despite my understanding of these concepts (with the exception of basic complex analysis), I can't solve a lot beyond pre-calculus by hand. Wolfram Alpha is a very useful tool.

If you're familiar with water hammer, that is precisely what is happening here. Water will flow downhill, and once it's moving, it has kinetic energy. If you suddenly slam a valve closed, all of that kinetic energy has to go somewhere; typically into the nearby plumbing, causing a sudden jolt of increased pressure ("water hammer"). In this case, there's a convenient place for it to go: up the tube. And so it does. If there's a large mass of water and/or it's moving quite fast, it can have a lot of kinetic energy. This increased pressure can be many times higher than the head pressure of the water's static mass under gravity, which can cause big problems if there's no safe place for all the energy to go. Water is relatively incompressible, so a typical solution is to add a surge tank nearby that contains a compressible fluid (gas) - this way the energy will be spent more gently by compressing that gas, causing a much more gradual change in pressure instead of a massive spike. The water will surge into that tank, and as the gas in the tank is compressed it will start pushing back, slowing the water down gradually until it stops flowing, reverses, and eventually the compressed gas will push that extra water back out of the surge tank and the system will return to static equilibrium.

[@youngbloodsuccaa]

Firehose water hammer 😳

[@solandri69]

He glossed over the important part. The kinetic energy of the water cannot exceed the potential energy it had when it was in the bucket. So on the face of it it would appear that even if you made this 100% efficient and recovered all of the kinetic energy, it could never pump water higher than the source. The key is that this is only true for kinetic energy per unit volume of water. By setting a long train of water in the pipe moving, you're able to harvest the kinetic energy from the entire volume of water in the pipe, to pump a small volume of water higher than the source. It's analogous to dropping a basketball with a tennis ball stacked on top of it. When the basketball hits the ground and tries to bounce, its kinetic energy gets transferred into the tennis ball, causing the tennis ball to fly much higher than the drop height. Whereas if you just dropped a basketball, it couldn't bounce higher than the drop height. That's why the waste water coming out the lower valve is important. Without it, this would happen just once, then the kinetic energy in the water remaining in the pipe would be insufficient to get it back up to the source bucket level (the basketball just rolls around on the ground instead of bouncing). And the whole thing would stop. By allowing water to bleed out the bottom, you allow the train of water in the pipe to build up to full kinetic energy again, so you can repeat the process.

[@bobguy1167]

The surge tank you're describing is actually also pictured. That tube on the left that is capped is filled with normal air (just like a surge tank) and it takes up some of the water hammer pressure. Once the valve is closed the air tries to return to it's normal pressure and pushes more water up the tube. This is why you see the ram closes so suddenly, but the release of water out the top is just a BIT more gradual. It's because of that little surge tank taking up some of the pressure. His setup doesn't really need it for the demo to work, but it's extremely important for people that are using ram pumps to move hundreds of thousands of gallons of water per year, in their hydroelectric off grid pelton systems.

[@ericlotze7724]

The KZbin channel “Practical Engineering” has a great video on Ram Pumps which is worth a look in my opinion (Also Water and Steam Hammer for more technical and non-ram pump applications)

[@jonslg240]

I'm proud of your commit, sir. He could have made that analogy. Also: *He could have EASILY obtained efficiency data from this.* Also, he could have cut the rubber tubes to length.. It feels pretty lazy for the standards we've learned to expect from him, because it would have only taken him 10 more minutes plus 5 minutes of thinking to pull off a FAR better experiment than the one he did here. Him not even explaining what the original poster explained here was extra laziness.

[@frederickwelham3829]

Ordinance Survey maps show hydraulic rams which were installed in Victorian times to supply water to houses many metres in elevation higher than the source, usually a spring. They also used a device called a jack pump.

[@09jt1]

Love this little engineering masterpiece. Actually invented in England by Clockmaker Whitehurst ~1772, or in France about the same time. Montgolfier had one. A Swedish engineer, find one in France early for 1800-something.,BUT it hadn't any automatic valves. You have to open/close valves manually. That Swedish guy, engineer J O.Lundberg, took a patent in 1896 ( begun selling them in ~1893). Product was baptized Vädur, Vædur (Ram in English). Try to get a pic in here, no it didn't work my way. It was sold all around the world. Sold in it's original design until ~2000. Perhaps today. As young boy I saw that miracle! Without any external power keep pumping 24/7?? All the water flooding around was the power I understand (and forget) as an adult. I think, easy estimated, 90% was spilled to pump the left 10%. But it pumped it to a HIGH level. I still love it, and among bicycle it's a sustainable invention.

[@taiyoqun]

Ram pumps take 2 cm of potential energy and transform it into 5 m of potential energy. Yes, they lose a lot of water to do so, so it can't feed itself, but otherwise they are the closest we have to free energy. They are magic even if you understand how they work

[@altafnazir]

its not free energy, you have to pour water into bucket, and if bucket size is big, manual filling won't work, so you will need a machine to fill bucket, and hence it's not free.

[@ryanl7564]

This is very interesting! How come you have that long capped pipe afterwards?

[@NomadSoul76]

I'm interested in that myself. What it might be is basically an empty tube filled with air. Something like this can be used in household plumbing to prevent water hammer, the air acts like a spring because it is compressible. When the sudden pressure spike of the water comes through that second valve in the system, I think it might tend to compress the air in that tube and then the air will decompress more slowly and feed the water into the rest of the system where it exits from the top. It may be that without this the sudden pressures shake with shake the whole system and possibly waste the energy he's trying to use to lift the water.

Route the water from both sources so that it turns turbines connected to small generators connected those generators to a pump that pumps the waste water from the bottom back up to the bucket. You could even add a turbine and generator in the initial drop tube to get additional energy to add back in to the system. While is is still not going to be a perpetual motion machine, it will allow the system to run longer.
