Question

The deepest point in the ocean is 11km below sea level, deeper than Mt. Everest is tall.What is the pressure in atmospheres at this depth?

Answer 1

In Newtons/m^2 (also called Pascals), the pressure at that depth (H) is
(rho) g H =
1025 kg/m^3*9.81 m/s^2*11*10^3 m

I have used the density (rho) of sea water. To convert to atmospheres, use the conversion factor
1.013*10^5 Pascals = 1 atm

I get a bit over 1000 atm. See what you get

Answer 2

Thanks, I got 1100atm.
