How do you calculate how much mass a balloon can lift?

Answer:

1. List all of the variables given. Mass of balloon = 80 kg. Volume of balloon = 1200 m3 Density of Helium = .18 kg/m3 Density of Air = 1.3 kg/m3
2. Determine the the total mass that can be lifted by the helium balloon. Mass lifted = mass of the volume of fluid displaced. Mass = (1200 m3)( 1.3 kg/m3) Mass = 1560 kg.

What is the mass of a balloon filled with air?

The weight of an empty balloon: Pretty much nothing (scales say “0”). So here is what they did next: They blew up the balloon and weighted it again. My scales say “2 grams”. Weight of a balloon full of air: Still not much, but more than an empty balloon.

How much weight can a cubic meter of helium lift?

The density of helium at 1 atmosphere pressure and 0°C temperature (that’s called “standard temperature and pressure”, STP) is about 0.18 kg/m³. The lifting force is the difference between the weight of a volume of helium and the same volume of air, or 1.02 kg/m³. For 80 kg you need 80 / 1.02 = 78.4 m³ of helium.

How much helium does a 36 balloon need?

To fill a 36″ Balloon fully you need 15 cubic feet of helium equivalent to one F50 canister.

How do you find the density of a gas balloon?

Subtract the weight of the empty balloon, mB, from the weight of the full balloon, mGB. This will give you the mass of the gas alone, mG. Divide the mass of the gas, mG, by the volume, V, of the gas to find the density of the gas, DG.

Is a balloon filled with air heavier?

When you fill a balloon, you have to compress it to expand the rubber. Compressed air has more weight as a similar volume of air at normal atmospheric pressure. Therefore the balloon is heavier than an equal volume of air. A balloon will gauge more when it’s full of air, it basically has more mass.

How much helium does it take to lift 100 kg?

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.

What is the lift capacity of helium?

How much weight can a helium balloon lift? A standard helium balloon can lift approximately 0.03 pounds or 14 grams.
