Submarine's maximum safe depth

In summary, a submarine's maximum safe depth depends on its type and model, with modern military submarines having a depth of 300-400 meters and civilian submarines having a depth of 150-200 meters. The determination of a submarine's maximum safe depth involves design, engineering, and extensive testing. Going beyond the maximum safe depth can result in structural damage or collapse. It is possible to increase a submarine's maximum safe depth, but it requires significant modifications and testing. A submarine's hull and internal pressure systems are designed to withstand the pressure at its maximum safe depth.

Homework Statement



A research submarine has a 17cm diameter window 6.0 cm thick. The manufacturer says the window can withstand forces up to 1.0X10^6 N. What is the submarine's maximum safe depth? Assume that the pressure inside the submarine is maintained at 1.0atm and that the density of seawater is 1030 kg/m^3.

Homework Equations



p = p0 + pgd

The Attempt at a Solution



I tried the following

1.0X10^6 = 1.013X10^5 + (1030)(9.8)d, and I got d = 89.033 and of course it was wrong.

Related to Submarine's maximum safe depth

1. What is a submarine's maximum safe depth?

The maximum safe depth of a submarine varies depending on the type and model. Generally, modern military submarines have a maximum safe depth between 300-400 meters, while civilian submarines have a maximum safe depth of around 150-200 meters.

2. How is a submarine's maximum safe depth determined?

A submarine's maximum safe depth is determined by its design and engineering, taking into account factors such as water pressure, hull strength, and the ability to withstand external forces. Extensive testing and simulations are conducted to determine the maximum safe depth of a submarine.

3. What happens if a submarine goes beyond its maximum safe depth?

If a submarine goes beyond its maximum safe depth, it can experience structural damage or even collapse due to the immense pressure of the water. This can be dangerous for the crew and can also lead to the loss of the submarine.

4. Can a submarine's maximum safe depth be increased?

It is possible to increase a submarine's maximum safe depth through modifications and upgrades, but this requires extensive engineering and testing to ensure the safety and functionality of the submarine. It is not a simple or easy process.

5. How does a submarine withstand the pressure at its maximum safe depth?

A submarine's hull is designed to withstand the immense pressure of the water at its maximum safe depth. The shape and thickness of the hull, as well as the internal pressure systems, help to distribute and balance the external pressure and keep the submarine safe.
