What is the greatest water pressure of the Pacific Ocean?

Answer 1

The water pressure is measured in bar and is the weight of the water above you. The water pressure is linked to the depth in the way that for every 10 meters you go down you have 1 more bar of pressure. So to find the presure at any depth you simply divide the depth in meters by 10. So the greatest pressure in Pacific Ocean depends on its max depth.

The Mariana Trench in the western North Pacific is the deepest point in the Pacific and the world, reaching a depth of 10,911 metres (35,798 ft).

10911 meters / 10 gives: 1091 bar pressure at bottom of Mariana Trench.

To be 100% accurate you should actually divide by 9.81 because this is the gravity constant and multiply by a little because this is saltwater and not freshwater and then multiply by a little because the temperature changes down the water column and this gives you a little higher pressure like approx 1151 bar.

Since 1 bar is 14.504 psi this gives you

1091 bar is the same as 15824 psi. 1151 bar is the same as 16694 psi

1091 bar is the same as 15.824 psi -> 15,82 thousand psi

1151 bar is the same as 16.694 psi -> 16,69 thousand psi

To convert bars to kilopascals, multiply by 100, so 1091 bar is 109100 kPa
