10 lines on compressed air
Answers
Compressed air is air kept under a pressure that is greater than atmospheric pressure.
Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles.
Brakes applied by compressed air made large railway trains safer and more efficient to operate.
Compressed air brakes are also found on large highway vehicles.
Compressed air is used as a breathing gas by underwater divers.
In industry, compressed air is so widely used that it is often regarded as the fourth utility, after electricity, natural gas and water.
However, compressed air is more expensive than the other three utilities when evaluated on a per unit energy delivered basis.
It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical.
Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres.
An air bubble in the blood stream is known medically as an embolism, a dangerous medical condition in which a blood vessel is blocked, in this case, by an air bubble. An embolism of an artery can cause coma, paralysis or death depending upon its size, duration and location.
I hope it will help you.
1) Compressed air: Compressed air is a gas or combination of gases that has been put under greater pressure than the air in the general environment.
2) Compressed air is an important medium for transfer of energyin industrial processes.
3) Compressed air in spray cans is often used to clean things that are especially delicate or sensitive, such as keyboards.
4) It is commonly used in power tools such as air hammers, drills, wrenches, and others as well as to customise paints.
5) Compressed air is much and more greater than atmospheric pressure.
I think this much is enough.. for compressed air
