What else can I help you with?
Why deep sea divers not using ordinary air?
Because they have a air tank to help them breath.
How does an air pocket underwater remain constant when divers expel air into it?
Air pocket formed is due pressure. Air made of mass and and if enclosed areas, water rush in and push air against wall. If not enclosed, air will reach top surface as air bubble.
Can you use helium in an air balloon not hot air just ordinary party balloons?
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
Can a diver go seven miles down to the bottom of the ocean?
they can go 1000 meters down !!! . but they have to have a tree near them Additional: There have been navy tests in cambers which divers have been under pressure to simulate dives to 2000 feet. Since most of the body in made up of uncompressable water in theory a diver could go to unlimited depth as long as the air he is breathing is reduce in oxygen and nitrogen to keep him from convulsing. And at a high enough pressure so his lungs would be equalized.. Question is how long would it take to come back up from deep deep "dive" with all the decompression needed. Tim
Does an ordinary electric fan cool the air?
An ordinary electric fan does not cool the air; instead, it creates airflow that helps evaporate moisture from your skin, making you feel cooler. The fan circulates room temperature air, which can aid in heat dissipation from your body. However, if used in a closed space, the fan will not lower the actual temperature of the air. It is most effective when combined with other cooling methods, such as air conditioning.
Why deep sea divers not using ordinary air?
Because they have a air tank to help them breath.
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.
How do divers get their air?
Divers typically get their air from a tank filled with compressed air, which they carry on their backs. This tank is connected to a regulator that controls the flow of air, allowing divers to breathe comfortably underwater. In some cases, divers may use alternative gas mixtures, such as nitrox or trimix, to extend their dive time or enhance safety. Surface-supplied diving systems are another option, providing air through a hose from a support vessel.
Why do scuba divers need math?
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
What is the mixture of gases in a deep sea divers air tank?
95-98%helium 2-5% Oxygen
Why isn't it a good idea for divers travelling by air straight after a deep dive?
So they dont get the bends and the co2 levels in the body have time to equalize.
How deep can a hard hat diver dive?
Hard hat divers can typically dive to depths of around 300 feet (about 91 meters) using surface-supplied air. However, with specialized equipment and techniques, some divers have reached depths of up to 1,000 feet (approximately 305 meters) or more. The actual depth limit can vary based on the diver's experience, the conditions of the dive, and the equipment used. Safety protocols and decompression considerations are critical at these extreme depths.
What is the name of a compressed air cylinder used in skin diving?
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
What has the author Peter B Bennett written?
Peter B. Bennett has written: 'The physiology and medicine of diving and compressed air work' -- subject(s): Deep diving, High pressure (Science), Physiological aspects, Physiological aspects of Deep diving, Physiological effect, Submarine medicine 'The Physiology and Medicine of Diving' 'To the very depths' -- subject(s): Anesthesiologists, Divers Alert Network, Divers, Biography
How can the increase in the level of nitrogen be avoided by deep sea divers?
By breathing nitrox (gases where the %O2 is higher as compared to air) or mixed gases (e.g. adding in helium) so that the partial pressure of nitrogen is reduced.
Why cant ordinary air be used if a dive is very deep?
Oxygen is toxic above partial pressures of 1.6, which is a little less than 8 atmospheres, or 230 feet.
What kind of gas do divers use?
Divers use 21% Oxygen and 79% nitrogen while underwater. It results in the same exact air we breath on the surface.
