This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.
The valves on industrial, medical and diving cylinders usually have threads or connection geometries of different handedness, sizes and types that depend on the category of gas, making it more difficult to mistakenly misuse a gas. For example, a hydrogen cylinder valve outlet does not fit an oxygen regulator and supply line, which could result ...
The exhaled gas from these devices is discharged to the environment, and the oxygen is lost, so they are less gas-efficient than closed circuit rebreathers, but do not have a carbon dioxide scrubber or counterlungs, which is a saving on weight and bulk, and make use of the oxygen available in the ambient air, so their efficiency is better at ...
From sitting in your vehicle while your gas pumps to using inappropriate containers for spare gas, here are 9 things you should never do while pumping gas.
This is a non-comprehensive list of inflatable manufactured goods, as no such list could ever completely contain all items that regularly change. An inflatable [1] is an object that can typically be inflated with a gas, including air, hydrogen, helium and nitrogen. Some can be inflated with liquids, such as waterbeds and water balloons
A gas extender is an apparatus for extending the endurance of a breathing gas supply, for example, by re-using some of the gas in a rebreather circuit.The term is relatively frequently applied to semi-closed rebreather systems, but is not used very often. [29] [30] [31] Compare with oxygen conserving device and demand pulse device
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap.
