Siphon Explained by Doctor C

- A water siphon is a very common tool, but few really understand how water can flow uphill. Here we see that a siphon works because water acts as if each molecule were chained together; there can be no gaps in a constrained water column.
You can also see that an actual chain behaves exactly like a fluid siphon. Here is it easy to comprehend that the heaver external section of chain pulls up and out the lighter section of chain in the vessel. - Наука та технологія
Seriously this was a lifelong question you just answered.
Great Idea! I may need to add to this video. I'm grateful that people are interested enough to suggest means to improve the explanation.
I really like your videos is easy to understand when you explain it. I HOPE YOU UPLOAD MORE VIDEOS. Thank you very much for your knowledge. You really share passion when explaining. Thank you
Yes, that's a good idea. A lot of folks have a problem with that being left out. I'll add text explaining the atmospheric pressure is what makes the stream act like a "chain." Thanks.
Absolutely brilliant, nice video.
Wowww, just wowww man Doc! U nailed the explanation man! Keep it up! Absolutely understood it!!
super explanation at the end of this video....thanks
Let me just say the the intent was NOT to say a liquid is like a chain. Atmospheric pressure prevents the liquid from separating when in tension. Under this condition, liquid DOES behave like a chain in that it does not separate.
This metaphor make the concept easier to comprehend to non-scientists. That's all.
Oh doctor C you crack me up
That's pretty cool, with the chain example. Note to self (remember): water acts as a chain.
Is that work if the surface is higher than the source of water like if the water is in deep well?
Thank you
I don't agree with the theory of the description here - a siphon works because of hydrostatic pressure - it is not like the chain in the small jug. the hydrostatic pressure at the top of the higher liquid is greater than that of the lower level of liquid hence the surrounding air pressure all around us "squeezes"the liquid along the tube. to start it off you have to clear the tube of the air to get the pressure along the line to balance - so if you have air pressure in the line it doesnt work hence you usually have to suck a siphon to get it moving to balance the pressure out - this is not what happens with the chain; the chain falls because of gravity and because it is physically connected - it starts falling because the gravity force is great than any friction force holding the chain in the jug - that is not the principle of how a siphon works - not the principle of hydrostatic pressure which is how a siphon works.
⚠️ God has said in the Quran:
🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )
⚠️ Quran
He said water behaves like a chain, because of the push of atmospheric pressure and pull of gravity plus..adhesive forces bw the water molecules ! Which is the missing component in ur theory!
Yeah the guy said it flowed uphill and then down….
Thank you, someone who can actually teach….
What did you drink?
What is equation with
siphoning
Bell siphoning
Herons fountain
Inverted siphoning
So we got maximum free energy ?
can we reverse the process? could it be possible to make the water go back up to that beaker(say it is in a higher elevation) by making the column on the tube that goes to the beaker way longer than what goes to the other glass?
just away I don't know but you can make the water travel out of the cup through a tube and to a higher elevated cup if the lower cup has more pressure on the liquid in the cup. Maybe by using pistons... I just described hydraulics lol
Unfortunately, no. The surface of the water in the container relative to the length of tube determines the differential in "weight" of the water column.
Great!
El flujo de un recipiente a otro a través de la manguera no tiene relación con la cadena, el flujo se debe a un equilibrio energético entre los dos extremos.
The how is easy?
The why? Not so many videos on that.
Doctor C! is that alcohol?
interesting
Dr C! That was vodka man!
The continuum theory cannot explain why siphon doesn't happen in vacuum.
I would love to see the snide critics to better.
I don't understand
Interesting and easy to understand demonstration, but I don't think it's accurate. First off, you statement that the customary explanation involves the weight of water in one leg pulling the other leg is incorrect. The customary explanation is a differential in pressure.Regardless, the maximum lift height of a water siphon is about 10m or 33 feet. Assuming the water siphon is analogous to the chain siphon, then this implies there is no limit to the height of the water siphon. I've never heard of a siphon that works at greater than 10m.
When I was young, me and my mama had beef
17 years old, kicked out on the streets
Though back at the time I never thought I'd see her face
Ain't a woman alive that could take my mama's place
Suspended from school
And scared to go home, I was a fool
With the big boys breaking all the rules
I shed tears with my baby sister, over the years
We was poorer than the other little kids
And even though we had different daddies, the same drama
When things went wrong we'd blame mama
Everything he says wrong but then again, people still belive we live on a ball magically there is a thing called gravity without a reality. That's why siphon can never be explained without throwing the gravity so idiots can say "oh I get it" lol!
No thats how it actually works, the hydrogen bond is strong enough with the right pressure.
choakoncawk Hahahaha
What the fuck
koolaid
food coloring is bad for your health
This was not very helpful
yea a chain is just like a liquid lmfao this was the worst demonstration ive ever seen..
JRN2222 A chain is just like liquid that doesn't want to separate in a tube because that would create a vacuum which would pull the water back together due to the atmospheric pressure on the water that does act like a chain you dummy. It's a great visual metaphor.
horrible explanation.
what's so hard to get? it's a chain like attraction between the water molecules. the rest is up to your education to fill in the lines, it's complicated but people don't spoon feed you anything. water is polar so the molecules will attract one another especially in a small tube where intermolecular forces prevail over many others (see capillary action), and pull on one another as long as it's given an initial momentum (when you manually set up the siphon) and the mixture of those two causes the water to be siphoned out. I only came here because after a few problems in fluid mechanics i wanted to understand more in depth how water can travel upwards without a force. and it's true in the end, it cant do that without the "pulling effect" of the chain of h2o molecules.
