Most very deep dives are done in trimix, which is a mix of oxygen (actually very little of that), helium and nitrogen.
For really deep dives, divers use heliox, which is a mix of pure helium and oxygen.
And for really stupidly deep dives, divers use hyrdeliox(hydrogen, helium and oxygen).
What else can I help you with?
If the air you breathe is 80 nitrogen 20 oxygen what the ratio in a dive cylinder?
In a typical scuba diving cylinder, the air mixture is compressed and stored. The ratio of nitrogen to oxygen in the dive cylinder will be the same as atmospheric air, around 78% nitrogen and 21% oxygen. However, very specialized mixes may be used depending on the dive plan.
Is nitrogen gas poisonous?
Good and Funny question. Nitrogen is all over the world. It occupies large proportion of air we inhale. If it was poisonous, all the livings would be dead! So, its NO ***************2nd Opinion ************* Not always so funny. At normal atmospheric pressure we don't get enough in our blood to affect us, but if we breathe air at high pressures, as scuba divers do, the amount of nitrogen in us goes up. At a depth of 100 ft, it starts to intoxicate the diver, and at 300 ft it can cause a loss of consciousness and even death. That's why divers don't use regular air at extreme depths.
Can compressed nitrogen explode?
Yes, but it is a mechanical explosion and not a chemical one. The pressure of the gas cause the gas to store mechanical energy. And if circumstances permit, like a weakening to failure of a compressed gas cylinder with high pressure nitrogen in it, there will be a mechanical explosion. Such things have been known to occur - with catastrophic results. Nitrogen will not burn in the conventional sense, so it won't explode like, say, hydrogen.
What are four uses for oxygen?
Supporting combustion: Oxygen is essential for combustion to occur, helping to sustain the process. Cellular respiration: Oxygen is crucial for the process of cellular respiration in living organisms, where it's used to produce energy. Medical therapy: Oxygen therapy is used to treat conditions like hypoxia and respiratory failure by providing extra oxygen to the patient. Ozone production: Oxygen is used in the production of ozone, which has various industrial applications such as sterilization and water treatment.
How can you get oxygen underwater?
You can bring oxygen underwater by using scuba diving equipment, such as a tank of compressed air and a regulator that allows you to breathe while submerged. Alternatively, some marine mammals like whales and dolphins are able to store and use oxygen efficiently in their bodies to stay underwater for extended periods of time.
What is the air mixture in scuba?
The air mixture in scuba diving tanks is typically compressed air, which consists of about 21% oxygen and 79% nitrogen. This mixture allows divers to breathe at depth without experiencing adverse effects of high pressure.
Why only oxygen is not used in tanks of scuba divers?
Naturally the air we breath has 70% of nitrogen and only 21% of oxygen, this is done is scuba diving as well. Just oxygen is not enough for living, while oxygen is essential one.
Why do you need oxygen cylinders when you go scuba diving?
The simple answer is ... you don't. A majority of scuba dives use compressed air in the cylinders. Therefore you don't need "oxygen" cylinders. HOWEVER, if you are a diver that is diving on Nitrox, in which divers change the amount of oxygen vs nitrogen in their air, then your tank needs to be "oxygen clean" because you are putting oxygen in first, then nitrogen.
Give one use of oxygen?
For oxygen masks for firefighters, scuba divers etc
If there is no oxygen on the moon then how does the man in the moon breathe?
By oxygen tanks - similar to SCUBA divers.
Scuba tanks have wh at noble gas in them?
Scuba tanks are typically filled with compressed air, which is a mixture of oxygen and nitrogen. However, some scuba tanks may also contain a noble gas such as helium as part of a special gas mix called trimix, which is used for deep dives to reduce the risk of nitrogen narcosis.
What is in scuba tank?
Usually AIR, which is 21% Oxygen and 79% Nitrogen...BUT!!!! It could have been used for Nitrox, which is elevated Oxygen, If you dont KNOW for sure what is in it, DUMP the gas and refill the cylinder.
What are the factors that determine the no decompression limits for scuba divers?
The factors that determine the no decompression limits for scuba divers include the depth of the dive, the time spent at that depth, the diver's previous dives, and the breathing gas mixture used. These factors affect the amount of nitrogen absorbed by the body and the risk of decompression sickness.
Why do scuba divers carry oxygen cylinders?
So that they may breath underwater.
Is there scuba masks with oxygen in them?
Scuba masks do not contain oxygen. Instead, scuba divers rely on a separate piece of equipment called a tank or cylinder to supply compressed air or a breathing gas mixture for underwater breathing. The scuba mask's purpose is to provide a clear field of vision and to create an airspace for the diver's eyes and nose while underwater.
Where can one purchase a scuba regulator online?
Scuba regulators, also called 'diving regulators', are vital for scuba divers to properly obtain oxygen from a tank. Regulators are available for purchase through diving specialty stores such as Prime Scuba, House of Scuba, and Divers Direct.
What are the gases that scuba divier breathe?
In recreational diving, most divers use compressed air (as in the normal air we breather at the surface). Some divers are also trained to use special gas mixes called Nitrox which have a higher oxygen content and lower Nitrogen. Professional (or commerical) divers tend to use more advance mixes such as Heliox or Trimix which combine Oxygen, Nitrogen and Helium.
