## Homework Statement

A submarine called the Deep View 66 is currently being developed to take 66 tourists at a time on sightseeing trips to tropical coral reefs. According to guidelines of the American Society of Mechanical Engineers (ASME), to be safe for human occupancy the Deep View 66 must be able to withstand a pressure of 10.0 {\rm N} per square millimeter.

To what depth can the Deep View 66 safely descend in seawater?

## Homework Equations

p = M/V (density formula)

P = F/A (pressure formula)

P

_{g}= P - P

_{at}(gauge pressure formula)

P

_{2}= P

_{1}+ pgh (Pressure with Depth)

g = 9.81

density of seawater = 1025 kg/m

^{3}

## The Attempt at a Solution

Here is what I know about the problem:

I know that p = 1025 kg/m

^{3}

I know that g = 9.81

I know that P

_{1}= 10 N because its given in the problem

But I don't know P

_{2}or h

I have tried to figure a way to do the problem but I don't know how to start it. Any advice would be greatly appreciated. Just an advice on how to go about the problem on finding P

_{2}.
