Dive Into Life Submariners

The submarine is one of the results were amazing technology. When the Afghan war broke out, some of the Tomahawk missiles fired from American and British submarines. Its role in winning the war is quite large. For the crew, the battle is not just happening on the surface of water, but also under the sea. Real battle going on inside the submarine itself. They had to fight with boredom, fear, and isolation. A crew of submarine warfare can live for months, even years, under the sea. Space is very limited. A fighter submarine has a length of 85.5 meters by 9.5 meters wide and 9.5 meters high. Daily Mail journalist, Danny Danzinger, recently tried to ride the Royal Navy's submarine the British navy for three weeks. He wanted to know more closely the life inside the submarine. In his report, Danzinger admitted, while in the submarine, life is slow and monotonous. Meals per week have never changed. People and environments encountered always the same from day to day. "They do a very dangerous and should have high discipline in conditions that are totally uncomfortable. But they are not awarded anything," Danzinger said. Living in a submarine is far from pleasant. There was no sunlight or fresh air intake. Living alone, surrounded by walls of iron and steel. No windows or exits. So, how do they get the air supply? There are three main problems is crucial for a submarine which is always a top priority, namely to maintain air quality, maintain a supply of fresh air, as well as maintaining the room temperature. Maintaining air quality is not easy. Therefore, the inhaled air contains four elements, nitrogen (78 percent), oxygen (21 percent), argon (0.94 percent), and carbon dioxide (0.04 percent). When breathing air, the body takes the oxygen and convert it into carbon dioxide when released. Incurred while breathing air that contains 4.5 percent carbon dioxide. The body of nitrogen and argon can not change it. In order for the air quality is always maintained in a submarine, three things must be considered is the oxygen levels should always be in sufficient quantities to be inhaled. If the percentage of oxygen levels drop, the crew will experience shortness of breath and died. Carbon dioxide must be immediately removed from the room. If there's too much, gas is very dangerous because it will turn into toxic and deadly. Finally, water vapor that comes out during breathing must also be eliminated. Oxygen can be obtained from high-pressure air tank or oxygen generator (obtained by the method of water electrolysis, which separates the elements hydrogen and oxygen from H2O), or the method of "oxygen canister", which release oxygen to the heat of chemical reactions. Carbon dioxide can be removed from air by chemical processes, namely by using soda lime (sodium hydroxide and calcium hydroxide) in a tool called scrubbers. Carbon dioxide is captured from the air by the lime soda through chemical reactions and purged of air. While the humidity can be eliminated by using a neutralizing moisture or by chemical processes. The purpose of moisture reduction to prevent rust on the vessel wall or other critical equipment. In addition to other gases, like carbon monoxide or hydrogen, caused by a ship's machinery or cigarette smoke, can be removed by burning. While the dust and par Another small tikel removed by using air filters. So, what about water? To get clean water not as complicated to control air quality. Almost all of the submarine is equipped with water purification devices, which convert the salty sea water into fresh water. Water purifying machine will heat the sea water to evaporate. The goal is to remove salt from water. Furthermore, the purified water was cooled and stored in a tank of clean water. A water purifying machines capable of producing 38-150 thousand liters of water per day. Freshwater is used to cool electronic equipment, such as computers and navigation equipment. Moreover, for everyday needs, such as cooking, drinking, and bathing. One thing that is not less important is to keep the air temperature remains comfortable. Because the submarine is always under the surface of the water, the air temperature inside the cabin can reach 4 degrees Celsius. Typically, to warm the room, use the heater. While the electric power derived from nuclear reactors (if it is a nuclear-powered submarine), diesel engine, or batteries. Although the facility is complete, Danzinger claims have absolutely no interest to submariners. *** [MAILONLINE | HOWITWORKS | FIRMAN | KORAN TEMPO 3615]
