Helium is also used as an ingredient in deep-sea SCUBA tanks, which require a mixture of helium, oxygen and nitrogen to combat the effects of high pressure disorientation that results from breathing ordinary air. Why Is the Helium Running Out? The United States established the National Helium Reserve in 1925.

Helium's profile including the latest music, albums, songs, music videos and more updates.

50/50 is too much helium. Any more than 25 % helium gives me a dirty-sooty weld as possible. I mix at about 15% when I get over 1/4", but below I just use argon. If you have both bottles, you could mix them to reduce your Helium percentages. Maybe half one bottle, and half the other. At times I like to run about 5% helium.

The People's Network is made possible through sophisticated, open-source technologies that aim to create a truly decentralized and trust-less model for building wireless infrastructure. The network uses two units of exchange: HNT, a new cryptocurrency, and Data Credits. Our novel proof-of-work algorithm enables Hotspots to be rewarded trustlessly.

So, 8.5% hydrogen in helium appears to be non-flammable, whereas anything above 8.7% is flammable. Eight percent hydrogen really doesn't provide much in the way of cost savings. You probably ought to consider another question concerning your airship business. Are the cost savings by using a 8.5% mixture of hydrogen worth all the trouble and ...

Squeezed hydrogen and helium don't mix. The results of a high-pressure experiment that re-creates the temperatures and pressures inside Jupiter and Saturn reconcile disparate space-based observations. By mass, the giant gaseous planets Jupiter and Saturn consist of about 75–85% hydrogen and helium. (Uranus and Neptune, by contrast, are ice ...

Helium was detected in the sun by its spectral lines many years before it was found on Earth. Appearance. A colourless, odourless gas that is totally unreactive. Uses. Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers.

Helium is one of the basic chemical elements. In its natural state, helium is a colorless gas known for its low density and low chemical reactivity. It is probably best known as a non-flammable substitute for hydrogen to provide the lift in blimps and balloons. Because it is chemically inert, it is also used as a gas shield in robotic arc ...

The air we breathe is largely made up of nitrogen. Nitrogen weighs 1.2506 grams per liter. Helium weighs only 0.1785 grams per liter. The lightweight helium displaces the heavier air. The pressure from the air around the balloon (along with the temperature of the air) "pushes" the balloon upwards. It is very similar to how objects float in ...

The speed of welding brought by helium comes at a price. This mix will cost you a bit more money, but if your priority is speed over the cost, then this is the best mix for you. Trimix — 90% Helium, 7.5% Argon, and 2.5% CO2; Altogether, the three materials create the …

The helium repeatedly slid from one end of the cylinder to the other. The authors overcame this difficulty by devising a mixing mechanism internal to the cylinders. The molecular weight of helium is 4.02, and density is .1786 kg/m^3 at standard temperature and pressure. For nitrogen, molecular weight is 28.02, and density is 1.2506 kg/m^3.

Helium is the second most prevalent element in the universe, after hydrogen.However, the atmosphere contains only 5 ppm volume of helium. Helium concentrations in seawater are no higher than 4-7 ppt. Concentrations are relatively low, because helium as a noble gas only occurs as separate atoms, and usually does not react with any other particles.
