How to lift water up to 5 metres without using a pump?

[Ravi Singh choudhary]

I was asked how you can lift the water up to 5 meter but you are not allowed to use any kind of pump. What I thought; seal the container from where water is being lifted. Connect it with a pressure vessel at some height which is containing steam and water with valve in between them. By default valve is closed. Now wait for steam being cooled in the vessel that would create a vacuum inside the vessel. Then open the valve. One more thing vessel is kind of cylinder and Kind or cover is placed at top of inside the vessel which will go down during cooling of steam; so that I would be able to make vacuum that is effective as I am stopping any kind of evaporation or boiling. There is a provision of tap below vessel to drain out some water also. After all these things I ended with a reciprocating pump only.

Please help

1) With the water in a container, use an elevator to lift the container - or a crane or just carry it.
or
2) Boil the water.
or
3) Place the container onto a land mine.

Be a tree?

That means capillary action

That means capillary action

yes and isn't a pump

Is "the water" flowing or static?

1. Evaporate it, then catch the rain.
2. Make a still with the condenser 5 m up
3. Blow wind over water until waves are 5 m high.
4. Waterspout.
5. Freeze it, then throw snowballs
6. Cloth treadmill on an incline, wet at the bottom and a wringer on top.
7. A birdbath. Let the birds drink, then fly up and eliminate.
8. A funnel feeding a tube at the base of a waterfall. (5m? Who knows?)
9. A Catapult throwing water balloons.
10. A Rocket
11. Use an elephant with a long trunk.
12. Put a plastic barrel with water in front of a wall. Run into it at high speed with a car.

Give me a day, I'll think of another dozen. I bet half the PF members can do the same .

Siphon action. Use a pipe more than 8m long

 

[mrspeedybob]

What is your definition of a "pump"?

 

[CWatters]

Siphon action. Use a pipe more than 8m long

How does that work?

 

[EngPhy]

Add stones until the level rises to 5m!

I think number 12 constitutes a most basic form of pump and should be disqualified. And half of 11 if the elephant is spraying the water instead of sucking it up.

1. Did anyone mention a geyser?
2. Or the man made version of a geyser: a percolator.
3. Parts of Scandinavia are still recovering from the last ice age. The land is rising 1 cm/year. So in about 500 years, all the lakes will be raised 5 m.
4. Tsunami
5. Splash. A big (or fast) object striking the surface of water creates a splash that could be 5 m high.
6. Laser levitation. Science experiments move particles with lasers every day via radiation pressure. How about boosting a single H20 molecule 5m by laser?

Hold the water still. Move the Earth 5 meters with a lever.
Put the water in a boat, and wait for a 5 m wave, or a 5 m tide, or global warming.
Turn the water into hydrogen and oxygen in a balloon. The buoyancy of the hydrogen will cause it to rise. Then light a match.
... that could also be done continuously. Electrochemically turn water into hydrogen and oxygen in a pipe. The gas pressure would cause it to expand out the top of the pipe. Where it could be burned carefully and collected.

Siphon action. Use a pipe more than 8m long

But less than ~ 9.8m. At sea level. At high altitudes 8m is already too long.

 

[rude man]

How does that work?

ρgh = p_atmosphere.

 

[jbriggs444]

ρgh = p_atmosphere.

If you are trying to siphon water five meters with an eight meter pipe, you will have problems. You need five meters up and then at least five meters back down. The total had better be greater than ten meters or you won't have a siphon. You'll have an empty pipe instead.

You're still lifting water up 8m. The problem stated " ..how you can lift the water up to 5 meter ...". It didn't say you couldn't then bring it back down to below the start level.

Right. But an 8 meter pipe won't reach. If you want to lift 8 meters, you need at least 16 meters of pipe.

Who said anything about an 8 meter pipe? The problem did not preclude a 10 or 11m pipe ...

Then I guess a convection loop would be allowed.

 

[CWatters]

How about the Leidenfrost effect or does that count as a pump (skip to 1min 40s for the best demo)..

Does that answer your question?

 

[kenyanchemist]

Siphoning is still technically a pump... just reciprocal

 

[kenyanchemist]

Try getting an object with enough density to exert a gravitational pull on the water then place it more than 5m above the water

 

[jbriggs444]

Easier to just invert your coordinate system.

 

[kenyanchemist]

Ionize the water then get a strong enough potential difference

A few maybe not already mentioned:-
➊ Furiously stir the water or spin the bowl (wide mouth, 5m tall with sloping sides) and the water in it will climb up the sides and spill over.
➋ Plant bamboo around your small bottle of water, arrange to delicately support its weight on the growing tips.
➌ Suspend your bicycle over the bowl of water and spin the rear wheel faster and faster until its rooster tail attains 5 metres AGL.
❹ Add a few drops of detergent and blow bubbles to rise 5 metres, catch each and recover one drop of water. ☁

What do you mean by "pump"?
Do you mean an actual motor pump or the principal of a pump?

 

[arydberg]

Go the the Bay of Fundy and wait for the tide to come in.

 

[anorlunda]

I count 45 unique answers so far. I wager that PF members could come up with many more.

My favorite so far was this one, which is so subtle and clever that I didn't get it at first glance.

Easier to just invert your coordinate system.

In other words, if we invert the definitions of "up" and "down", than water always runs uphill.

Change the direction of gravity by bringing the Earth closer to a more extremely massive cold body as evaporating has already been mentioned.

Attach the container to the ground and quickly accelerate the ground downward.

Don't do anything and tell the professor it will happen, you just have to wait a bit.

 

[jbriggs444]

You could pour the water into the Mississippi in Saint Paul, and wait for it to flow down past New Orleans. In the course of this flow, it will have moved farther away from the center of the Earth by significantly more than five meters. But the approach of spinning the container has already been mentioned, so this hardly counts as original.

 

[anorlunda]

Deep water in the ocean will rise naturally due to thermal or salinity unbalances.

 

[EnumaElish]

Just add (more) water

 

[Shafia Zahin]

Add some solids or liquids to the water which have a higher relative density than the water.

assuming you have cold and warm/hot water to an enough extreme you can push them towards each other in a cylinder with warm under cold. make sure the pipes are possitioned so that the water rides the outside of the cylinder and the water goes the same direction do to the circle. have an overflow at the top so the water that comes out is 5 meters high . the effect is a tornado of water that overflows into a channel that is effectively 5 meters high

take the moon or any other large mass body you can find and attach a rope to it.Then use the rope to hold it in place right above your water source and if needed use the rope to pull the moon closer and your water will go upwards.

Otherwise I would put an empty tank with an open top the +5 meters and wait for rain.

It depends on the volume of water you need to lift, the number of time cycles you can lift the water in, whether these cycles constitute a pump, and so forth. Does "pump" mean moving parts? You can create a solar "pump" without having any moving parts except for gate valves, maybe a check valve. If this is an exercise, saying the system can remain closed, and the lifted water doesn't have to be utilized, it simplifies things even more. I am limited as to what image edit software I have available, but here goes:

The water is contained in the bucket at the bottom. The top has a chamber that is sealed to the standpipe, with the top of the standpipe above the bottom of the chamber to allow for catchment of overflow. With a limited diameter not as much vacuum will be necessary to lift the water based on mmHg/in², but this will increase the amount of cycle times required.

Paint the upper chamber black. During the day, the upper chamber will heat, forcing air out and bubbling out through the bottom of the standpipe. In the evening, the air will contract, atmospheric pressure will force water up the standpipe to be collected in the catchment basin, provided the difference in heat is great enough to differ with ambient air temperature.

EDIT: If you need to collect the water from the catchment basin for use, I'm sure you can figure out from here how to add the gate valves to ensure vacuum loss isn't created, etc.

Another idea: have toddlers step on and or try to plug all the nozzles at your nearest splash pad. Some of those nozzles can build enough pressure to 'lift water' much further than 5 meters!

I think OP was asking for real help. But on the fun side, might I suggest diamagnetic levitation?
