Why did it work?

 

GO HERE:

 

 

because the water is moving. you can get it to go uphill by converting kinetic energy to potential energy. much the same thing happens when a skateboarder uses a quarter pipe to get some air time.

I thought Force1 at pipe inlet is greater than Force2 at pipe outlet.

yes, the pressure is greater at 1 than 2 because of depth. but that isn't the cause.

I can't be bothered to look at the vids. Is the bloke taking a bucket of water up a hill?

nah its a sloping pipe in moving water.

Correct it is moving uphill. The video proves it. A pressure differential is created.

So? Do you think you have found a flaw in the laws of physics?

 

Hint: You haven't. Google the phrase "dynamic pressure" to see why.

I don't believe that Cyclonebuster actually attempts to point out a flaw in the laws of physics. He's merely trying to find out what the physics are behind his "trick". And I believe that this has been answered by now.

So how far uphill can I move it this way?

depends how fast the water is moving relative to the pipe.

 

look up bernoullis equation. this will allow you to calculate it for a specific velocity.

What about cold deep water? How cold of water can I move uphill?

as long as it isn't ice you can do it.

The density hardly changes, so it doesn't matter how deep or how cold the water is.

A certain velocity will translate into a certain height above the water level.

 

Look up the equations and new words that you learned in this thread... You cannot learn physics without studying, I'm afraid. You really have to put a bit of effort

I did do the effort and built the pipe to show the naysayers! Watch the video it proves it.

What if the surface water is 90 degrees and the water at depth is 60 degrees?

yep, it'll still work. and you should specify what temperature scale you are using. i'm going assume you mean degrees farenheit as 90*C water isn't usually found in nature.

 

we'd preffer it if you used celsius here as it is the most common measurement scale globally anda lot of our membership is international.

I mean in F not C correct!

What if the surface water is 90 degrees and the water at depth is 50 degrees? I am looking for an average temperature of 70 degrees F..

it'll work even if the lower water is at 32*F (0*C) and the upper water is 212*F(100*C).

 

if the water is liquid, it will work.

Can you show me the math proving it works? My math is very basic.

Or is the video proof enough?

You might want to look at the "hydraulic ram", which uses the kinetic energy of streaming water to pump a smaller volume of water to quite great heights.

Thanks I have heard of them before but I have never seen one.

Now I have watched the vid. I wish I hadn't bothered.

With the right casting and costume "someone carrying a bucket of water up a hill" would have been much more fun to watch.

With the right casting no costume "someone carrying a bucket of water up a hill" would have been much more fun to watch.

 

fixed!

I challenge you to do the test. You will see it works! It cost me about 15 bucks.

there's no need, we know that you can raise water by using the kinetic energy of the water itself.
