Question

The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure (in atm) due to the ocean at the bottom of this trench, given its depth is 10.3 km and assuming sea water density is constant all the way down. atm

Answer 1

`P = 103867260` atm

Step-by-step explanation:

The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column

Thus,
`P = \rho*g*h`

Substituting the given values, we get -

`P = 1029` kg/m3
`* 9.8` m/s^2
`*10.3 *1000` meters

`P = 103867260` atm
