 How do submarines work? How does this submarine move under water?


 Submarine is one of the largest machines in the world which can work even in bad conditions. Where there is no presence of light, where there is eternal darkness and also lack of air, and all around is water and water in the deep sea withstanding the heavy water pressure and advancing towards the enemy side. There is no end to people's curiosity about submarines. I think common people like you have many questions about submarines.

 Today our topic of discussion about submarines is:-


When was the submarine first discovered? What is its history? How many types of submarines are there? How do submarines work? How does a submarine float on water and how does it go under water? Where does the oxygen of the submarine come from? The biggest question is how is the life of a submarine under water? How do they spend months in the deep sea? We will discuss the answers to all the questions today.


 What is a submarine? That is, what is its history?


 A submarine is a type of watercraft.

 or water graft. Not only can it move on water, but it can also move freely under water. Measuring the depth of the deep ocean is a very simple matter. And the submarine is very good at attacking the enemy. Cornelius Deville is regarded as the inventor of the submarine. He first invented submarines for navigational communication in 1620. He served in the Royal Navy under King James I of England. The first submarine built in England was made of wood. And he was wrapped in skins. It could go 3 to 4 meters deep in water. Then gradually people's inclination towards making submarines started increasing. Various types of submarines began to be built in the eighteenth century. In 1980, the first steam-powered submarine was invented. Then diesel, gasoline, then electric powered submarines were developed. Then some military battles were fought with their help. The prevalence of submarine use in World War I is particularly notable. In 1950, nuclear powered submarines were operated for the first time. Currently nuclear powered submarines are being built in large numbers. The body of these submarines is made of steel. Various advanced technologies are used in such submarines. Enemies hiding in the sea are very easy to spot. Submarines are used for exploration and research for the advancement of marine science. Currently, these submarines are used for underwater archeological surveys to attract tourists.


 How do submarines work?


 Many people may wonder how the submarine moves, how it floats on the water and how it goes under the water. The matter is not that complicated. Submarines work according to the formula of the ancient Greek scientist Archimedes. His formula is Perastike theory. Based on this theory, Deville invented the first submarine in 1620. Generally the amount of water the vessel displaces for its own volume. Its weight is greater than the weight of the ship. Then the ship floats on the water. And if the weight of the ship can be increased in any way, the water displaced by the ship is less than the weight of the ship, then the ship will sink. Submarines and Floats on Water Submarines sink and float by increasing and decreasing their weight. To put it more simply, when there is air on a bottle, it floats on top of the water, but when it is filled with water, it sinks. If the water in the bottle is removed by some method under water and air is filled inside it, the bottle will float again, this is exactly the formula that submarines operate. Submarines have a number of patch tanks for submerging themselves in water. The bulb of the tank is opened and sea water is introduced into it. And by giving compost to the submarine, water is taken out of the Payson tank and air is introduced. Then it becomes lighter and floats on the water. This does not create any pressure inside the submarine. Because it uses high quality steel and metals like titanium. Due to these metals, submarines can withstand all kinds of pressure not only in water but also outside water. I have said so much about floating on water and sinking under water.


 How does the submarine move forward?


 A submarine has a wake behind it. That drives the submarine forward through development. Submarines can usually move at a speed of 60 to 50 kilometers per hour.


 How is the supply of oxygen under the water of the submarine?

 We know that oxygen is essential for our respiration. Lack of oxygen inside the submarine under the sea is very normal. Oxygen generators provide oxygen for snakes. Which works in the process of electrolysis. Oxygen builds up in submarines throughout the day. Or when the computer detects low oxygen levels and when the subject of oxygen comes, another question must come to people's minds that is what happens to the carbon dioxide that is released in the submarine? We all know that we take in oxygen and give out carbon dioxide. It is very important to remove the carbon dioxide released from the submarine. Otherwise it can cause death and therefore chemical processes are followed to remove carbon dioxide from the submarine. It is called small land.


 What is the source of submarine power?


Submarines are mainly of two types. 1. Diesel electric engine, 2. and nuclear reactors or nuclear powered. Many of us may think that submarine engines run directly with the help of diesel. But in reality this is not the case. Diesel engines require a lot of oxygen to run which is not available in submarines. Besides, diesel engines produce a lot of smoke. It would be extremely dangerous for the people inside the submarine. And the diesel engine makes a special sound. And if this engine is the main engine then the enemy will find the submarine very easily. In reality these diesel engines spin a generator. And the electricity from that generator charges the submarine's batteries. And during this battery charging, the submarine floats on the water. And when the charging is finished, the battery turns the motor. A propeller connected to the motor rotates. Under this rule the design driven engine runs underwater. But there are several modern diesel powered engines available today. However, they can work underwater for quite some time. On the other hand, a large number of nuclear submarines are being built these days. These nuclear submarines do not require any oxygen to run. For this reason no additional battery is required separately. Turbines are rotated by nuclear reactions and this rotational power is used to drive propellers. And it generates the electricity needed to do the submarine's other functions, which is why nuclear submarines don't have to surface as often.


 How to see from the inside of the submarine?


 The control room of the submarine is in the middle of the submarine. From here it is almost impossible to see the deep sea beyond with the naked eye. Submarines use solar to solve this problem. The submarine's used solar system uses sound waves to provide a one-dimensional image of its surroundings. This image shows what is around the submarine. How deep is the sea, where is it high, where is it low or where are the enemy submarines? Or at shallower depths, the submarine can float its bow above the water to see what's there.


 How is the life of the soldiers in the submarine?


 The role of army is very important to protect any country. But do you know how difficult situation Baini Sanad has to face to keep an eye on the enemies coming by sea in defense of the country. They risk their lives to protect the country from under the sea. And this is why the army needs submarines. Through submarines, they keep an eye on the enemy from the deep sea. The missions of naval personnel who go to eat are so secret and so classified that sometimes they themselves do not know what mission they are being sent on. The toughest job in the world is working on a submarine. A submarine is a very confortable and unmanned vessel. It operates at depths of 300 to 1,000 feet of sea water. And destroys the enemies by identifying them from a distance. Did you know that naval personnel in submarines do not see the light of day day after day? Sometimes they don't get to see the light of day for a month. Then they have no connection with the outside world. There is no contact with family members. Usually their mission is about one month. Sometimes soldiers do not know in advance when their mission will end. They work underwater all the time. You will be more surprised to know that soldiers who live in submarines do not even get a chance to take a bath every day. Once in 5 to 6 days there is an opportunity to take a bath once with everyone's consent. That is why they are given special clothes and these clothes are not like ordinary clothes. Clothing is provided so that soldiers can wear one outfit for three to four days. And then they throw away these clothes with special chemicals attached to them, which will protect their body from bacteria. The soldiers and officers who go on the submarine all wear uniforms. There is no rank in this. They all live together like a family. A very mild curry is served with rice and bread in Very Nice. Special care is taken during the preparation of the food so as not to produce excess. Because a small mistake can destroy the entire submarine. Being inside the sea, they cannot perceive any difference between day and night. Soldiers get very little time to eat. Average is only 12 to 14 minutes. Due to the many types of materials inside the submarine, there is very little sleeping space. A small cabin sleeps 5 to 6 people together. They get only five to six hours of sleep. Each person in the subfield has an important role to play. Because one person's mistake can cause a great danger to the entire submarine. By now you must understand just how difficult and how risky submarine work is. We are proud of those brave soldiers who never hesitated to lay down their lives for the safety of the country, leaving behind their families, friends and happiness. We should all respect and salute their sacrifice.
