Depth and pressure in a submarine

In summary, as a submarine dives, the pressure on its hull increases due to the depth, but this is compensated by increasing the thickness of the hull. The thickness of the hull only determines its strength and ability to withstand pressure before imploding. Therefore, the correct answer is either b or e.

Homework Statement



As a submarine dives, the pressure on its hull..

a. remains constant
b. increases
c. depends on the decrease in volume of the submarine
d . decreases
e. depends on the thickeness of the walls of the submarine

Homework Equations



P = F / A

The Attempt at a Solution



Not a.

Not c. since the volume remains constant. Ballasts are simply used to allow in water in order to dive...

Not d. Pressure increases as one goes deeper.

I think the answer is either b or e. The pressure on the hull does increase but that is compensated by increasing the thickness of the hull...

The thickness of the hull only determines it's strength ie the pressure it will withstand before imploding . Therefore correct answer to you problem is ?

Yes that makes sense. Thus the pressure on the hull increases as the submarine dives. Correct?

That is correct .
 

1. What is the relationship between depth and pressure in a submarine?

The deeper a submarine goes, the higher the pressure becomes. This is because there is more water above the submarine, and the weight of the water creates pressure on the vessel.

2. How is pressure measured in a submarine?

Pressure in a submarine is typically measured in bars or pounds per square inch (psi). This is done using specialized instruments called pressure gauges.

3. How does pressure affect the human body in a submarine?

As a submarine descends to greater depths, the pressure increases and can cause discomfort or even injury to the human body. This is why submarines are equipped with pressurized compartments for the crew to stay in.

4. Can a submarine withstand extreme pressures at the bottom of the ocean?

Yes, most submarines are designed and built to withstand extreme pressures at the bottom of the ocean. They are made with strong materials and have thick hulls to withstand the immense pressure.

5. How does a submarine adjust its depth and pressure?

A submarine has ballast tanks that can be filled with water or air to change its buoyancy and adjust its depth. By controlling the amount of water in the tanks, the submarine can change its density and therefore its depth and pressure.
