Depth and pressure in a submarine

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between depth and pressure in a submarine, focusing on how pressure affects the hull as the submarine dives. Participants are examining the implications of pressure changes and the role of hull thickness.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore various answer choices regarding how pressure behaves as a submarine dives, with some questioning the assumptions about hull thickness and its role in pressure resistance.

Discussion Status

There is a recognition that pressure increases with depth, and some participants affirm this understanding. The role of hull thickness is discussed in terms of strength rather than affecting pressure directly, indicating a productive exploration of concepts.

Contextual Notes

Participants are navigating the implications of the homework question, with some expressing uncertainty about the correct answer while clarifying the relationship between pressure and hull characteristics.

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 .
