In 1987, a British man, Ian Ashpole, set the reported world record for highest helium-balloon flight. Using 400 helium balloons with radii of one foot, he achieved the height of one mile, 1,575 yards without any of the balloons popping. This figure is the highest recorded altitude of a helium balloon. Calculating Altitude.

Dec 10, 2007 · Lifting power comes from buoyancy. Buoyancy comes from volume. Suppose a balloon filled with helium can lift a 1lb = 454g weight. The total force on the balloon in equilibrium is . 0 = B - G - 454g. where B is the buoyant force and G is gravity on the balloon itself. For argument sake, suppose the balloon weighs nothing.

Question on lifting power of gases | Physics Forums

physicsforums.com/threads/question-on-lifting-power-of-gases.113982/

Mar 12, 2006 · What produces the "lifting power" is the buoyant force due to the air pressure acting on the balloon. That buoyant force depends on the volume of air displaced, not on what's inside the balloon. But the load that the balloon can lift is reduced by the weight of the balloon material plus whatever is inside the balloon.

How Much Can a Helium Balloon Lift? - Cockeyed

cockeyed.com/science/helium/helium.shtml

The lifting power of the helium gas was being offset by the weight of the two pennies, the baking cup, the tape, the ribbon, and the balloon itself. Those weights were just slightly greater than the lift of the helium gas: 1.3 grams greater, as shown on the scale.

Why do we use helium and not hydrogen balloons ...

thenakedscientists.com/articles/questions/why-do-we-use-helium-and-not-hydrogen-balloons

Nov 24, 2007 · In order to get a floating balloon you want a gas which is as light as possible. Helium is quite a lot lighter than air: it's about an eighth of the density of air. Hydrogen is about a sixteenth the density of air, so it'll float in air and will in fact float upwards. You'd have thought that hydrogen would be a better gas as it would give ...

Lifting Power Of Helium Ground Level

Balloon Lift - University of Hawaii

chem.hawaii.edu/uham/lift.html

While atomic hydrogen is only one fourth the weight of atomic helium, hydrogen forms a diatomic molecule as a gas, and thus has a molecular weight of half of helium, reducing the lift advantage. Since hydrogen is explosive in mixtures with air of more than 4 percent, it is a great fire hazard and serious explosion hazard in large quantities.

Helium and hydrogen have no power to lift anything. A lighter-than-air craft is able to fly because it is lighter than air (i.e., it weighs less than the volume of air that it displaces.) Helium or hydrogen are used because they fill the space, and they are lighter than air.

ProgrammingAI: How much weight can a Helium balloon lift?

Aug 23, 2012 · This is equivalent to say that 1 litre of Air weights 1,275g, whereas 1 litre of Helium weights 0,176g. This means that a 1 litre Helium balloon (plus its payload) shall rise if the weight of the balloon (without gas) plus the payload is less than 1,275-0,176g= 1,099g (if the weight is the same the balloon will float and not rise).
