Depth and pressure in a submarine

  • #1

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?
