Water flows downwards but it canbe made to flow upwards--by which method?

Answer 1

thats what u have fountains for (pressure systems) and suction systems (like how u sip out of a straw)

Answer 2

Capillary action is the easiest. Half-fill a bowl, drape a cloth over the edge with one end in the water and the other hanging outside, wait a while - whoops! You have an empty bowl and a wet floor.

Every time you flush the loo, water flows uphill. The pull of the handle creates a partial vacuum which pulls water up in the rising limb of the "siphon" device, and the cistern empties through the siphon by keeping the flow going, but every drop of it flows upwards before downwards.

Answer 3

If we consider gravity only then water can be made flow upwards by hydraulic pumps like centrifugal,turbine ,reciprocating,jet and many more.

If we neglect gravity then water can be made go (not flow) upward by capillary action.(Capillary action or capillarity (also known as capillary motion) is the ability of a substance (the standard reference is a to a tube in plants but can be seen readily with porous paper) to draw a liquid upwards against the force of gravity. It occurs when the adhesive intermolecular forces between the liquid and a solid are stronger than the cohesive intermolecular forces within the liquid. The effect causes a concave meniscus to form where the liquid is in contact with a vertical surface. The same effect is what causes porous materials to soak up liquids.)

Consider a trench surrounded by two hills: if water is comming from top of the hill and going to trench with high head then it will go upwards as long as energy is equilised.

OR you take a manometer(U tube type) connected to the discharge of blower then there will be a rise in opposite portion of the tube.It is a rise not a flow.

Answer 4

The water in the pipe isn't flowing below gravity - it is being pumped by using and the water rigidity is often particularly intense. this might rigidity the water to upward push upward if the breach is on the precise, and it could style a significant fountain. If the breach is in the decrease area of the pipe it is going to rapidly erode a hollow area, which will fall down from the precise and the water will then use this passage to get to the floor the place it could flow actual devoid of being impeded by utilising soil and rocks.

Answer 5

Water flows downward because it is pulled by gravity. However, if pressure is applied, it will flow from high pressure to low pressure (it's called head differential). Very similar to squeezing a 2 liter plastic bottle and having the liquid rise.

Answer 6

If the level of water is about 10 meters below the earth surface; stick a hose in it and suck the air out a little bit. Voila! the water is flowing up stream by the help of the atmospheric pressure.

Answer 7

use the pressure of gravity to cause a flow force to push the water upwards. Look at the roman aquaducts for inspiration. Civilizations have been doing this for centuries without the modern technologies.

Answer 8

Assuming that there is no external force applied other that gravity then water can flow against gravity [upwards] by capillary attraction. The same method is used when employing wicks in oil lamps.

Answer 9

I can't remember for sure, but I believe one race, (maybe the Greeks) accomplished this. I was unable to find any information on how, but was told years ago by my instructor that they or some other race had figured a way to accomplish this.

Possibly has to do with velocity of the water as it flows downward.

Answer 10

I have actually witnessed this in Colorado. Water flowing down from a higher source can gather enough momentum to carrying it uphill so long as there remains sufficient force flowing with it.

Much the same as a roller coaster will travel uphill for short periods due to its momentum.

Answer 11

Capillary action. Water can be absorbed up a porous material, against the force of gravity
