How a siphon (syphon) works

Explanation of how a siphon (syphon) works, and why the pipe does not empty.

For technical explanation of how tank of water drives a flow for a pipe at the base of tank, see:

Check out new content on this channel about the flume I built in my office:

Christ. Thank you! It took like 5 videos before I found this one that didn’t just say “and then the water is sucked out”. WHY is the water sucked out. Finally someone actually answered, thank you.

I got absolutely blasted off some Zaza and looked this up thanks for the explanation

[RiverReeves]

That was so incredibly concise. Thanks man!

[AnkitKumar-disj]

Finally understood this. Thanks for the video!

[luwyiki]

Thanks for making this video, its finally one that actually explains why this happens. Really appreciate it. :]

[carlomabinibayo]

Very concise and the explanation is on point.

[abidobby]

Than you for the wonderful explanation!!! <3

[Xero.Limitz]

Thanks for the physics refresher. Actually used it to drain a pool at home.

[dlsk]

That pipe needs to reach to the bottom of the container to have the same pressure as the first container

[swarajojha]

Thanks a lot. I love physics when i umderstand it. You did the job 👍

How would you explain that silphons also work in vacuum?

[josephpostma]

What happens when the lengths of pipe boths before and after the bend vary?

[aek]

YOu are creating a new education revolution

[tomwinkler]

Isn’t the pressure at the bottom of the tank much higher than the pressure at the top of the tank?
I would assume the pressure would not depend on the hight of the tank but rather just the hight until where the tube is inside the tank

[jamstawildman]

Nice explanation! One very minor point: the letter h is pronounced aitch- it doesn’t actually have an h at the start of itself.

[jayrashamiya]

Does this explain why it doesn't work when the height of outer pipe is higher than the height of water in the tank?

Show how much energy we got by siphon at maximum level
Stp and ntp
Siphon under high or low pressure created more energy efficient???

[hemantbisnath]

I need your help please. I am trying to drain off some water from a flooded piece of land to an area that's about 1 foot higher. Can you recommend something please?

[anilsharma-evmy]

Please show how much workdone in joules
One meter higher one meter cubic water volume tank siphoning by a pipe of one inch to ground tank

Vise versa
How much workdone required?
