Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
A sloped surface is used to help lift a load up.
If you mean vertical speed, you would need to know the amount of lift it's generating, its cross-sectional area and its drag factor (at least!). More info needed.
You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
It would take thousands of balloons to lift up the average house, as houses are heavy and balloons can only lift a small amount of weight. The exact number of balloons required would depend on the size and weight of the house, but it would be an impractical and unsafe way to try to lift a house.
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
10000000 helium balloons
No, balloons cannot lift a person off the ground. The amount of lift produced by balloons is not enough to support the weight of a person. Additionally, the laws of physics would make it impractical for balloons to overcome the force of gravity acting on a person.
Bigger balloons displace more air, creating more resistance against gravity, which slows down their descent. This increased surface area-to-weight ratio also helps them generate more lift, further reducing their fall speed.
lift = 1/2 air density x velocity squared x surface area

Rotation, no. Lift, yes. If you increase the surface area of the propeller, then you alter the lift to weight ratio.
To lift about 110 pounds it could take any where from 100 to 150 balloons to lift a person, a lawn chair, food, and many gallons of water. A man by the name of Kent Couch from Oregon demestrated this for us by flying from his home all the way to Idaho. I would'NT try this unless you have a parachute of some kind of device to help you have a better landing. The Balloons could be about the average party balloons (large ones) that are about 11in in diameter. Now remember this is very dangerous and could even be lethal.I hope this helped you.Thanks for looking--Tiana5701
