How much helium is needed to lift 1 lb?
You would need approximately 65 cubic feet of helium to lift 1 pound. Helium provides lift because it is lighter than the surrounding air, creating buoyancy.
How many kilograms of mass can one kilogram of helium lift?
About 0,85
How much helium is needed to lift an average human body?
Depends on the weight. Check the MythBusters website, they did an experiment on this.
How much helium is needed to lift 400 pounds?
To lift 400 pounds, you would need approximately 74.3 cubic feet of helium. Helium is lighter than air, so it provides lift when contained in a balloon.
How much helium does it take to lift 176 pounds?
1791.044776119403 cubic feet176 / 0.067 = 1791.044776119403
How much hydrogen is enough to lift up 1 kg weight from the ground?
The weight of standard air is 1.2256 Kg/ Cubic Meter The weight of hydrogen is 0.0857 Kg/ Cubic Meter The weight of helium is 0.1691 Kg/ Cubic Meter Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter These values are variable under altitude, pressure, temperature, humidity and purity of gas. Hope this helps you.
HOW BIG A HELIUM BALLOON WOULDIT TAKE TO LIFT A 175 LBS PERSON?
Let's ignore the mass of the balloon itself and the string/rope/harness/whatever that connects it to the person. We're also going to ignore the compression of the balloon; we can assume it's mylar or something and the helium inside is at normal atmospheric pressure (if the balloon is compressing the helium, it will need to be bigger, since the density of the helium goes up as the pressure increases).At around room temperature and ordinary pressures, helium has a density of about 0.164 kilograms per cubic meter. Under the same conditions, air has a density of a little under 1.2 kilograms per cubic meter. For a ballpark estimate, therefore, we can say that a balloon with a volume of 1 cubic meter will lift roughly 1 kilogram, which makes the calculation easy: to lift a 175 lb (80 kg) person, you need an 80 cubic meter balloon, which if spherical would have a radius of 2.67 meters or a little over 8 feet 9 inches.A helium balloon 18 feet across should be sufficient to lift 175 pounds. Now you know why blimps are HUGE.
How much helium would it take to lift the weight of the average person?
On average, a person weighs about 70 kg (154 lbs). To lift this weight, it would take approximately 70 cubic meters of helium at standard atmospheric pressure. This is a rough estimate and actual lifting capacity would depend on various factors like inflation pressure and volume.
How much hydrogen gas required to lift 1kg weight?
I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.
How many helium balloons does it take to lift a kilogram?
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
