Question

What is the water pressure at the deepest part of the ocean in the Challenger Deep in the Mariana Trench at 10,994 m below the surface.

Answer 1

The pressure is 107417976.4 N
`m^(-2)`

Step-by-step explanation:

The pressure of water at a given height/ depth can be determined by:

Pressure = σhg

Where: σ is the density of water, h is the height/ depth, and g is the gravitational force.

Given that; h = 10994 m, but σ = 997 kg/
`m^(3)` and g = 9.8 m/
`s^(2)`

Thus, the pressure of water at the deepest part of the ocean will be:

Pressure = 997 x 10994 x 9.8

= 997 x 107741.2

= 107417976.4

Pressure = 107 420 KN
`m^(-2)`

The pressure of water at 10994 m below the surface is 107417976.4 N
`m^(-2)`
