WebYou calculate how much helium you need to launch your payload with the knowledge that 1 cu.ft. of helium will lift 28 grams. You divide the weight of your balloon and payload (2400 g) by 28 g/cu.ft. to get the total number of cubic feet of helium required for your launch (2400 g ÷ 28 g/cu.ft = 86 cu.ft.). Hydrogen and helium are the most commonly used lift gases. Although helium is twice as heavy as (diatomic) hydrogen, they are both significantly lighter than air, making this difference negligible. The lifting power in air of hydrogen and helium can be calculated using the theory of buoyancy as follows: Thus helium is almost twice as dense as hydrogen. However, buoyancy depends upon the differ…
