Submarine how does it work

However, the use of subs are not only limited for those things above. Normally, they can also be used to recover lost items when a ship sinks, and even as a tourist ride to look for exotic view of the deep water. Generally, submarines can dive deeper than feet, and although they can stay under the water for long periods, they only limit the duration for 3 months due to the food and supplies stock they bring with.

Of course, submarines don't run by themselves. It takes several people to drive the submarines on the surface or when they're submerged. While they operate the subs, they should continuously keep in touch with shore bases and ships. That's why they have this equipment, designed specifically to contact directly or through a satellite.

They also make use of Very Low Frequency VLF radio when travels under the water, capable to reach the depths of 60 feet. Imagine you're having a big bowl of water and a cup. Then, you push the cup down to the bottom of the bowl.

Can you guess what will happen? Yup, of course the cup will sink. The reason is because when you put pressure on the cup, it will be filled with water. And apparently, the water adds the weight of the cup, causing it easier to sink. Taking the same principle, that's also how submarines work.

However, the key point for submarines to successfully dive is actually located on its huge tanks, named ballast tanks. At the top of the ballast tanks, there are valves that will open up when the subs are about to dive. Therefore, as the air on the ballast tanks is released, the tanks will fill in the seawater. If you ever have snorkeled or took a diving under the water, you will know how dark it is when you look around your surroundings.

Wonder What's Next? Try It Out Ready to dive even deeper to learn more about submarines? Enlist a crew of friends or family members to help you explore the depths of the following activities: Would you want to spend several months in a submarine at the bottom of the sea? Why or why not? Imagine what life would be like if you were confined to a submarine for an entire summer. What would you miss? What would be fun about it? Make a list of pros and cons and share it with a friend or family member.

Do they feel the same way as you do? What pros and cons can they think of? It may not be able to take you to the bottom of the ocean floor, but this homemade ship will put you in control of your very own submarine. So what are you waiting for? Are you ready to head down under, captain? Does water really exert force on submerged things? You bet it does! To learn more about this force, check out The Pressure of Water experiment.

William Sep 5, This is not a call by Australia to deploy nuclear weapons in our waters. In any case, Australia has never produced a nuclear weapon, and it is a party to nuclear nonproliferation treaties and international export control regimes, including the Treaty on the Non-Proliferation of Nuclear Weapons and Non-Proliferation and Disarmament Initiative. The tactical advantage of submarines comes from their stealth and ability to pinpoint targets secretly without detection.

Maintaining safety, for both crew and the natural environment, is crucial onboard any sea vessel. Hollywood movies such as K The Widowmaker , in which a nuclear submarine malfunctions on its maiden voyage, play on our emotions and our instinctive fear of nuclear radiation.

But advances in modern safety controls and procedures mean reactor accidents in submarines are hopefully now consigned to the past. The strategic and geopolitical outcomes of this policy decision are yet to be seen. Edition: Available editions United Kingdom. Become an author Sign up as a reader Sign in.
