what volume of helium would lift a pound A cubic foot of helium can lift 0 069 pounds due to the buoyant force of air To lift 100 pounds 1 449 cubic feet of helium would be required Helium is lighter than the
How much helium does it take to lift 1 pound Helium has an approximate lifting capacity of 28 2 grams per cubic foot To lift 1 pound 454 grams you would need approximately 16 cubic feet of helium How many helium balloons does it take to lift a pound One pound is equivalent to 453 592 grams Since each helium balloon can lift up to 14 grams you ll need 32 39 or 33 balloons to lift a one pound object

Helium can lift objects because it exhibits a buoyant force equal to the difference in grams mol At room conditions P 1 atm T 25 degrees Celsius what volume of helium One cubic foot of helium will lift about 28 2 grams so multiply the volume of the balloon by 28 2 Divide by 448 the number of grams in a pound to determine the number of pounds it can lift
You ll need around 12 grams of helium to fill a balloon with the desired lift Following the steps will help you find this exact amount To approximate the volume of the Gas capacity and balloons per helium tank figures are estimates Actual yield may vary 10 or more Lift ability figures are calculated at standard temperature and pressure at sea level in an

To calculate the lifting force of a helium balloon you need to determine its volume The formula for the volume of a sphere is V 4 3 r Once you have the volume multiply it by the How much helium does it take to lift 1 kg This would require a balloon with about a 15 5 foot diameter If instead you used small spherical one foot diameter balloons which
For a back of the envelope calculation the rule of thumb is that you need one cubic meter 1000 liters of hydrogen or helium to lift one kilogram so for 80 kilograms you need about 80 cubic You could manually find how many balloons you would need to lift anything by determining its weight measuring the size of the balloons calculating the volume of the
