Air pressure creates a 'base amount' of pressure to the Scuba divers. There is the effect that it adds on a small amount of pressure as well as the water pressure.
seriously? it is not diving and you don't scuba to breath in air.
recreational diving is usually done with 3000 psi of air in a certified SCUBA tank
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Normal pressurized air is used for scuba diving. However, you can get mixed gases for SCUBA diving such as Nitrox, which is mixed gases of nitrogen and oxygen. This is used by deep sea diving, but it takes special training.
In reference to scuba diving, "SPG" stands for "Submersible Pressure Guage", which tells you how much air is in your tank so you can resurface before going too low on oxygen.
A cardinal rule for scuba diving tanks is to never completely empty your scuba diving tank. When planning your scuba dives, it is important that you consider to complete your dive with enough air left within your scuba diving tank.
They have their place if you are diving in a dry suit for an extended time. If you are diving in a wet suit they would not be needed for obvious reasons. Scuba diving can dehydrate you from breathing the dry air in the scuba cylinders, so hydration is a must.
the amount of air in the tank per square inch. (p.s.i.)Improve answerPounds per Square Inch - so the amount of pressure exerted on the tank by the air under pressure in the cylinder of the scuba diver. The more pressure, the more compressed the air so the greater the volume of air compressed within the cylinder.for more on scuba diving, including equipment see the related link:
A person can only breath air that has the same pressure has his or her surroundings. Under water, the pressure will go up fairly quickly (every 10 meter / 33 feet of water exert the same pressure as that on the surface) and the scuba gear will make sure the diver gets air with the same pressure as that of the surroundings.
A scuba diver can purchase many things for scuba diving at the Air Hog online shop. They can purchase dive knives, dive lights, dive computers, and dive bags which will help them in scuba diving.
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
Technically, air pressure (surface atmospheric pressure) affects a scuba diver the same regardless of the depth. As far as total pressure goes, no diver has been to 1500 feet.
It passes thru the regulator where the surrounding pressure of the water regulates the pressure of the air in the line so that it is equal. This prevents any pressure differential that would make it hard to breathe.As for the air in the SCUBA cylinder, nothing happens to it as you go down. The pressure stays the same, etc. As to how breathing from a SCUBA cylinder works, there is an excellent answer under the question "How do you breathe underwater when you go scuba diving?"
Boyle's Law: (P1 X V1)/T1 = (P2 X V2)/T2 applies to scuba diving since there is a significant change in the pressure. As the pressure of the surounding water increases with depth, you are required to use far more air from the SCUBA tank to provide for your breathing. If you use one cubic foot of air at sea-level, doubling the atmosphereic pressure as you go down causes you to use your compressed air at twice the rate. By the time you get very deep you are using your air at a very high rate.
Its not really scuba diving but its considered scuba diving. Also known as the hookah system. its when you have a gas powered motor pumping fresh air to the person or person's diving below, there can be up to four people diving off of one hookah system. the benefit of this system is that there is no decompression time and you can be underwater pretty much all day if someone fills the gas tank on the engine pumping air. but you are kinda tied down to something so i don't think its true scuba diving.

Because the air is compressed so that the same amount of air fills much less space meaning more can be put into a SCUBA cylinder. Normally a tank will be pressurised up to around 3000psi/200bar of pressure.
The types of gas that a scuba diver can use are nitrox gas and pressurized, filtered air. These are the gases that they can use. The most frequently used gas for recreational diving is filtered air, but nitrox is used for tech diving, and for deep depth diving.
There will be air left in the tank. But it is not under enough pressure to come out of the bottle and into your lungs. There may actually be enough air to 'hiss' out once you get to the surface because it is no longer subject to the pressure of the water.
Literally, scuba diving means using diving underwater using Self Contained Underwater Breathing Apparatus.Conventional scuba equipment usually consists of a cylinder of compressed air (worn on the diver's back), and a "regulator" which converts the air from being highly compressed and delivers it to the diver at a breathable pressure.Scuba equipement also technically include rebreathers, which are a much more sophisticated form of diving equipment, whereby the air which the diver breathes is constantly recycled through a carbon dioxide scrubbing system.Scuba diving is now a popular recreational holiday activity, with over 10 million certified scuba divers worldwide.
The vest is simply called a scuba vest. It's to hold your air tank and regulators :)
The compressed air pushing against the inside of the scuba tank causes pressure inside it.
air, nitrogen, oxygen, trace gases, and sometimes helium
Force itself doesn't affect scuba diving. It's more the pressure.The further you go down, the more pressure there is.The more the pressure is, the more it effects the air spaces inside you.As the pressure it is, it compresses the air spaces inside of you, creating what is known as a squeeze. these are painful, and can prove dangerous, if you don't sort them out.To sort them out, you have to eitherHold you nose, and blow against it. (don't let the air come through your mouth!)Swallow and wiggle your jawThe important air spaces are in your ears, which you must equalize, and your lungs, but they equalize naturally when you breathe.
A bailout is an act of rescue, especially of a financial nature, or a backup supply of air in scuba diving.
