Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.

Why does a scuba diver need pressure in an air tank?

A scuba diver needs pressure in an air tank because water pressure increases and pushes down on their lungs as they go down. The air in your lungs is more compressed and more is needed to fill them completely.

What type of education would you need to become a scuba diver?

You need to take an Open Water scuba class.

What level of degree do you have to have to become a scuba diver?

There are no prerequisites to be a scuba diver, you just need to have the money. You do need to take a swimming test, but this isn't too hard. even a lousy swimmer can complete it.

Why do scuba divers need to exhale when they ascend to the surface?

As the diver ascends to the surface the external pressure decreases. If the air in the lungs were not exhaled, the volume in the thorax would expand, and the diver's lungs would explode.

Do you need experience to scuba dive?

I am a scuba diver. To start SCUBA, you must pass training. Many training centers are available in many areas.

What do you need to know to be a scubadiver?

To be a Scuba Diver you have to take a course in scuba diving which varies in cost depending on how old you are or where you are in the world .

Before a diver dives will he will take a deep breath or hyperventilate?

Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.

What happens to a scuba diver who has surfaced too quickly?

They will get the "bends" and need then to go into a compression chamber.

Why scuba divers use mixture of nitrogen and oxygen?

Because that is what air is made of and scuba divers need to breath air. It is however possible to increase the amount of O2 in the gas mixture if you are trained to breath Nitrox as a scuba diver and if you are a technical diver to add other gases such as helium to the mix. Recreational diver however normally breath simply compressed air.

What training do you need to become a scuba diver?

Go to the website for PADI to obtain complete details on their courses. There are other organizations, of course.

Why do divers need the newt suit?

It pervents the water pressure from killing the diver

What kind of training does one need to be a scuba diver?

There are many different things one must learn in order to be a scuba diver. Some of the more common practices are learning how to breath under water properly, learning how to put your gear on properly and learning safety tips in case something goes wrong.

Can you go on a recreational wreck scuba dive without being certified?

This depends on what you are doing. Usually you need to take an advanced diver course if you are wreck or cave diving.

How old do you need to be to scuba dive?

you need to be 10 to scuba dive.

Do you have to be a certain weight or body type to be a scuba diver?

No, you don't need a certain body type to scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.

What element do scuba divers need to prevent the bends?

Scuba divers need to decompress after a deep dive so that the oxygen levels in their blood return to normal before returning to the surface. Otherwise they will get the bends. A scuba diver will typically use his or her dive table or computer to figure out how many minutes they must decompress before resurfacing from the dive. Decompression takes place when a diver figures out the amount of time they need to wait at a certain depth under water before they can resurface. They also need to take into account how much air they have left so they can safely wait underneath the water for said period of time. A scuba diver will usually hold onto a drop line and simply breath and wait the allocated amount of time at the prescribed depth and only then safely return to the surface.

Why do you need a pressure regulator when scuba diving?

The pressure on a diver's body increases quickly with depth. At the surface we're all breathing air at 14.7 PSIg, or 1 "Atmosphere" (atm). Each 33 feet of sea water results in another 1 atm of pressure. This means, for example, that a diver's body is under a total pressure of 3 atmospheres at 66 feet of sea water (one of air, two of water). The human respiratory system is designed to operate at normal atmospheric pressure of 14.7 pounds per square inch. If we descend to 33 feet, the water pressure exerts a force of nearly 30 pounds per square inch on our bodies. Our bodies are incapable of breathing against that much pressure. A scuba pressure regulator is designed to deliver air at the same pressure as the surrounding water, allowing us to breathe.

How long does a scuba diver go to college?

Recreational scuba divers only need to undertake a short course to be qualified (or "certified" using industry jargon). The certification process for a basic open water diver normally takes about 5-6 days.Commercial divers usually undertake some kind of vocational training, but this is not usually done through a college or university.

How do you learn to scuba dive?

To learn to scuba dive you need to go a scuba diving course.

Why do scuba divers need to exhale air when they ascend to the surface of the water?

Number one rule of Scuba diving is never ever hold your breath the pressure changes when you descend and ascend could damage your lungs. When ascending a diver does not need to just exhale they breathe normally unless they are using an emergency ascend in which case, depending on which emergency ascent they are using and for what reason, ie out of air and so on, will exhale on the way up to again ensure the pressure changes will not cause their lungs from over expansion and bursting I hope this helps

Why does a scuba diver need more weight in the ocean than in fresh water?

Salt water is denser than fresh water, hence, it requires more weight to sink in salt water.

Why does your nose hurt when you go deep into your swimming pool?

Because of the pressure on your sinuses. It's kind I like when you need to even out the pressure on your ear drums when you scuba dive.

Can someone scuba dive to the HMHS Britannic wreck?

People have dived to the wreck, but as it sits in 400ft of water it's not for the recreational diver. You also need special permission from the Greek government as it is a war grave.

Why do scuba divers need increased pressure in the air tank?

The average human uses about 25 litres of air per minute (at sea level) and since a scuba tank is between 10 and 15 litres, if the gas wasn't compressed, it wouldn't even last a minute. By compressing the gas, it is possible to get 4500 litres of air or more in to the tank. This means the diver has much more air to use on a dive Air consumption per minute is tidal volume x breaths/minute. Average for an adult is 0.5 liters x 20 bpm = 6 lpm. Also the most common scuba tank holds 80 cubic feet or ~ 2300 liters.

What high school classes do you take to be a scuba diver?

You need to take an Open Water Certification course to become a SCUBA diver, but there are no pre-requisites. You actually only need to be 10 years old to enter PADI's first training program, and 14 for full certification, 16 for deep, and 18 for cave/cavern/wreck/search and recovery. However, though the physics are discussed, it is from a practical and not theoretical point of view, and does not require any previous knowledge of the topic. To be a technical diver or divemaster/instructor route, you should have a GED or diploma, and at least some physics knowledge.
