Do the math.

Energy loss due to viscous friction in the tubes and turbulence where the free stream falls into the funnel. If you had no energy loss, you could get it flowing and it would go forever. If you tried to use it to power a generator, it would slow the water down until it stopped.

The difference in height between the surface of the liquid in the container and the end of the tube which is hanging above the container is the length the liquid has to travel upward through the tube, but the energy required to cover this distance against gravity is not provided, because the tube ends above the liquid. Therefore the liquid will stop flowing. Also, this is a neat trick to do with carbonated sodas, as the carbon dioxide bubbles will force the liquid upward and make it flow anyway until the soda runs out of pop.

Does semi-perpetual (yes, dont need to be literal since even the universe will not live literally infinitely) motion exist, if we add a rule that doenst need to generate power to other devices?

>> No.7570558

>>7570514
But it does! I'm actually developing a method to make one of those generate energy and I'm gonna sell them on the cheap. You can pre-order one for a low $99, and be the first one to get it when they go into production (5-10 years from now probably)

Yeah, they are called planets. Or basically anything in space thanks to Newtons first as long as it doesn't crash into anything.

What math? Can you teach me?

>>7570535
I do not believe in perpetual motion, I just lack an understanding of physics to understand exactly why the water will not flow. I just cannot intuitively imagine it, I still do not expect it to work.

Nah, he's right. Google 'superfluids' for an example of what happens when most (but not all) of the energy loss is removed.

gee
I'm sure that somebody, somewhere has already asked this question to that exact apparatus
if only there was some kind of search engine which could give you answers within milliseconds, that way you wouldn't have to shit up this board with yet another perpetual motion thread
we can only dream that someday there'll be a website where you can type in "perpetual flow" and yield results about why the hell boyles flask doesn't work
I think we should call it "Google" once we develop such magnificent machine

I've actually conducted this experiment and found that carbinated fluids will cause the water to run until the fluid goes flat.

Try it yourself, its pretty fun.

just friction losses
everything from the tubes, to the wter tension and even air.
that`s what will stop the system. so as in any oter "perpetual motion" machine.

OP is confirmed retarded. Nobody is going to help you understand basic, common sense shit like this. Get fucked.

Siphon works when the Atmospheric pressure is acting upon the liquid which pushes to the straw. Then the gravity pulls the liquid inside the straw downwards. This does not work because the liquid that it drains from must be higher than to the container it will drain to.

>> No.7572593

ITT: This is a fluid, so does air. Liquid is fluid but fluid is not liquid. The more you know the more you understand.

>> No.7572601

The gravity pulls down the liquid inside the straw but then the straw goes upward. Therefore the gravity cancels out then this does not work.

>> No.7572607

Just don't think about perpetual motion. Laws of Thermodynamics already states it that it doesn't work!
