How much helium does it take to lift 50 pounds?

If you weigh 50 kilograms (about 110 pounds), then you weigh 50,000 grams. Divide your 50,000 grams by the 14 grams per balloon and you find that you need 3,571.42 balloons to lift your weight.

How many balloons does it take to lift a person up?

An average person weight about 136 pounds in the world, you will need a 16 foot diameter balloon. You don’t see a 16 foot diameter helium everyday, you may never saw it. If we try to use 1 diameter balloons to lift that person, we will need about 4500 balloons (Learn more).

How many helium filled balloons would it take to lift a person with a mass of 72 kg assume that each helium filled balloon is spherical with a diameter of 33 cm?

A person with a mass of 72 kg has a weight of 72 kgf, so performing the division you find: 72 kgf/0.021 (kgf/balloon) = 3429 balloons.

How many helium balloons would it take to lift Mythbusters?

The Myth – A 4 year old child can be lifted by a bunch of party balloons. Notes – It would require such a large number of balloons (3,500) to lift an average four-year-old girl of 44 lb just a few feet off the ground that there is no way the myth could have happened unintentionally.

How much helium would it take to lift 100 pounds?

The difference in the up and down force is 0.069 pounds. Therefore each cubic foot of helium could lift 0.069 pounds. In order to lift 100 pounds (which would include the weight of your load, the balloon, and the helium) you would need 1449 cubic feet of helium.

How much does a helium balloon weigh?

For one, you could look up the density of helium in a balloon, then multiply it by the volume you’d need so that it weighs five pounds. In air, helium has a density of 0.2 kilograms/cubic meter, so you’d need about 11 cubic meters of helium to weigh five pounds, which would be a balloon about three meters across.

How big does a helium balloon have to be to lift a person?

This would require a balloon with about a 15.5 foot diameter. If instead you used small spherical (one foot diameter) balloons (which holds about 0.526 cubic feet of gas), it would take over 2754 of them to lift the 100 pounds. Therefore a handful of small balloons will not lift you off the ground.

How much helium does it take to lift a house?

(Most houses weigh between 80,000 and 160,000 pounds.) Given that 1 cubic foot of helium can lift 0.067 pounds, it would take 1,492,537 cubic feet of helium to lift the house—or about as much as would be contained in 105,854 balloons, each 3 feet in diameter.

How many helium filled balloons would it take to lift a person with a mass of 72 kg?

3400 balloons
And we have 3 times 72 kilograms divided by 4π times this diameter divided by 2 to get radius and then converting the centimeters into meters by multiplying 33 by 10 to the minus 2, cube that radius times by 1.29 kilograms per cubic meter—density of air— minus 0.179 kilograms per cubic meter— density of helium— and you …
