Question

You want to use a mini submarine to explore a deep part of the Mariana Trench in the North
Pacific Ocean, which is 10,924 meters (35,840 ft or 6.8 miles) below sea level. A salesperson at
Hydrosubs, Inc., offers to sell you a mini sub that can withstand 1,200 atmospheres of pressure.
Will this mini sub work for your expedition? Please provide deatailed explaination. Thank You

(Note that the density of seawater varies with temperature, salinity, and pressure. With the help
of the Internet or some other resource, obtain the density of the seawater at the bottom of the
trench, then you may assume that the density is constant and equal to this value to solve the
problem

Explanation / Answer

Considering all conditions Density of sea water is taken=1029Kg/m^3

pressure, P=? gh

=1029*9.8*10924=1.10*10^8Pa=1087.9atm

Yes it will work.
