I know me too honestly. And every one here too, did u read the comments. We found it at last. N what's more we didn't even look for it. The motorcycle vid found us.
I can't rest easy before I've found out how rotating pumps work. I'm sure that's not the correct term though. Horizontal pump motion transformed to vertical suction? It's what the mechanized pumps do, but I'd like to see a hand powered one.
when the piston is pushed down, piston valves opens (helps to remove air inside the handpump) this create a compression of air on the upper side and when piston is pushed up, the piston valve closes (this create a vacuum between the foot valve and piston valve) and this force the foot valve to open due to extreme low pressure, hence their is a partial vacuum
When you force a certain amount of air to take up a larger volume (expand the container without allowing more air inside), you reduce the pressure inside that container. Look up Boyle's Law for a better understanding.
I have a question. If after the first use of the pump the main pipe fills up with water to the level of the outlet, does that mean that there’s always stationary water in the main pipe? And if so, does that contribute to bacteria formation in the water?
As per my own experience I say no, water doesn't remain indefinitely inside the cylinder. I guess it's because the valve doesn't seal completely the intake.
Old farm houses would mount a mini version right on the countertop beside the sink. Tin dipper hanging on the backsplash for a drink. People would draw from natural springs rather than dig a well.
Question for anyone here: wouldn't it be sensible to leave the handle in an upright position so that each time you pump in the future, you will always have water and not have to refill the pipe?
Can anyone explain that why does water rises in vaccum created by the hand pump, as there is no pressure underground to push it downward first. As usually atmospheric pressure does it.
Pretty sure this is wrong though. Vacuum can only suck water 33.9 feet, and most wells are deeper than this. I believe they have a shaft that runs all the way to the waterline.

@@sudeepsinghrawat528 no We use a long handle to pump and a magnet seal to reduce the pressure every time so we keep pushing every time We can make a very easy to use handle system which use gravity against gravity
Finally a clear explanation and excellent graphics about this simple mystery. Thank you.
This is not true the silinder is in the water level
Easily explained in just 2 minute.
Thank you for it
Now I can die peacefully:-)
just thought how many people used this and dont know princip of working, include me
ye bro add me in fornite im god at the game 'DEADSECK 1'' is my epic

It helped me this lockdown
This was so important to know honestly .
One of the Greatest of great invention!
So grateful to learn smthing which nearly messed my head for years
Hey bitch I'm hr again
Wait did I just talk to myself
Sorry fot my ignorance but I don't get how the vacuum generated
when the piston is pushed down, piston valves opens (helps to remove air inside the handpump) this create a compression of air on the upper side and when piston is pushed up, the piston valve closes (this create a vacuum between the foot valve and piston valve) and this force the foot valve to open due to extreme low pressure, hence their is a partial vacuum

Everybody surprised about the hand pump, but I want to know the science behind that little glass that never gets full.
Savage😁😂
Its acting the same way your mind does. Information in from one side, and out from other. " steady flow process"
@@sudeepsinghrawat528 😂😂
@@sudeepsinghrawat528 hahaha. Yeah. Maybe you're right
No water is wasted during the production of video.
SAVE WATER.
did you know that the water you're drinking is millions yrs old
Excellent explanation

I got the tingles!!
Very good explanation. Thank you for sharing!
now all I need is a truck to hit me and reincarnate into another world and use this knowledge whish me luck
I feel so dumb after having to search this up and watch the video XD. Also thank you for making this, it helped a lot.
Thank you for this useful video.
Explained in a vary simple way. ❤
“Very” simple indeed!
We are missing your videos

Who invented this wonderful system
I have a question. If after the first use of the pump the main pipe fills up with water to the level of the outlet, does that mean that there’s always stationary water in the main pipe? And if so, does that contribute to bacteria formation in the water?
As per my own experience I say no, water doesn't remain indefinitely inside the cylinder. I guess it's because the valve doesn't seal completely the intake.
How do you know that?
Very nice animation, helped me a lot!

I known about it...
But you explain it very well...👍👍
My exam today, after 15 min and I am watching this!!
what if , if i wipe out the 1 valve in lower part do youi think its still works ? please answer thanks
If you remove the check valve, water sucked from the well will return back when you lift the handle.
I thought it’s because of magic
It is magic,the video was fake
Aman Chaudhary “this* video is* fake”
@@benchmark7832 it is not fake
Suman Gupta, how do u explain water coming up from nowhere. FYI it is magic

It's incredible how big brain some ppl are. I just pass the butter lmao or in this case pump the water.
Could it be made to work like a siphon to get a constant flow? If so, a video like this would be great. Or a link.
siphons only work if the exit is lower than the water your siphoning iirc, otherwise you've just created a perpetual motion machine aha :D
What a simple technique....

Beautiful...
Very useful video thanq gain the knowledge
Finally my childhood question solved . 😅🦆
Super explanation. Thanks.
Very informative and educational!
Very nice explanation
Excellent graphics about this mystery❣️👍
Good one. plz make sanitizer pump video too.
Incredibly simple! But also jenious!
Genius*
Very Beautiful science 💝💝💝
Thanks for video
Non return valve are amazing. Still details on that are required
What about the bottom of the pipe in the underground.
Nice animation
Great job
but in punjab (india) .used some complex system.
Thank you .
Great channel.

What makes the foot valve have any movement?
The vacuum lifts it open and as it's ring closed the water pushes it back down.
Its a hinged joint there. So moment about hinge is possible with pull or push.
@@soldiers303 you are half right, half wrong.
Thank a lot for inform me
Question for anyone here: wouldn't it be sensible to leave the handle in an upright position so that each time you pump in the future, you will always have water and not have to refill the pipe?
You'd need more energy to pump water
wow👌 never seen it before
My question is, where does the water comes from. We hand one of these pumps at our home.
My question is, how deep can this pump pull water
Does water come out of spout during upstroke or downstroke. In my books it has written that during downstroke water comes out of the handpump.
This hand pump mechanism is deferent than our village hand pumps .
well done
How does this little force can suction out water from so deep
Thank you
Very nice
I am clearly understanded
Idk how I got here, but here I am.
How the lower valve is controlled there nothing attached to it
Can anyone explain that why does water rises in vaccum created by the hand pump, as there is no pressure underground to push it downward first. As usually atmospheric pressure does it.
Maybe because of suction by the upper valve
You answered your question yourself. Its the atmospheric pressure which let the water rise.
Thank you n god bles u
The valves open and close due to some mechanism or just by the weight of the water?
Pretty sure this is wrong though. Vacuum can only suck water 33.9 feet, and most wells are deeper than this. I believe they have a shaft that runs all the way to the waterline.
Hiw can i get allowed to use this video clip in a video im using about consistent work.
Good graphic
My handpump gives me water in 1 pump. you should increase your bore level, I will prefer more than 100ft+
Mansilayi 👍
Nice machinn👌
Please someone reply this does the water which fell off return to the ground?
Nice...
Thanks bro
More videos of important things..
Thật tuyệt 🎉❤❤
where is the water coming from though?
from the ground
Show a calculator so we found how much power we required for every kiloliter of water ?
amazing
But why partial vacuum is created in the first place? That part is not explained in the video.
Foot operated pump
Is more easy to work
Show some mechanical trick for it ?
Yes because foot can apply much more power than hand for same amount of work.
@@sudeepsinghrawat528 foot operated handpump are very easy to use
If we use hydraulic system then it becomes super easy
So try to make such design ?
@@anilsharma-ev2my but it will cost high if you use pneumatic /hydraulic system as you need a piston cylinder arrangement and compressor. This will consume electricity.
@@sudeepsinghrawat528 no
We use a long handle to pump and a magnet seal to reduce the pressure every time so we keep pushing every time

@@sudeepsinghrawat528 how i talk with you or discuss our plans on a sheet of paper
This older method is very dangerous
Up to how many feet we can use hand pump ?
When you know, please let me know
Is it harder to pump water from a hand pump if there's 2 extra holes aside from the main outlet?
No, work done is same, whatsoever the outlet may be.
Pump is very useful . very educative video
Thanks
Can this be used for pumping air in bicycles I mean the principle
Could you show me which software do you use to simulate this video?
Blender 3D
@@TecknoMechanics thank you so much
how foot valve opens?
What if it does not pump water? What's the usual cause?
informative❤
Who invented hand pump
I can die happy
Why some hand pump need water before pull the handle. After 3mins the water are gone.
Same as 'पिचकारी'
Bro how did u made this animation
Its simple, download the app.
Hello can anyone help me
how does the water moves upward when vaccum is created in 0:51
Please explain it and if you can suggest one video too
if you get a syringe and put it in water, when you pull the little handle up water comes through. it works the same way.
Nice
