what pressure do a human feel in water if he dives under 290m,and what happens to his body when he starts from 10m?
Answers
Answer:
When you freedive, even to a depth of just a couple of meters, your body is subject to the effects of pressure. These pressures are far greater than the ones we usually experience in our day-to-day lives, and without an understanding of how they affect the body and how to deal with them, serious injury can occur.
At sea level, the pressure of the air that surrounds us equal to 1 bar, which is sometimes referred to as 1 atmosphere. Dive to just 10 meters deep and that pressure is doubled – because water is much denser than air, it exerts a much greater compressive force on your body.
For every additional 10 meters deeper you dive, the pressure on your body increases by 1 bar. As you can see from the table below, our bodies are subject to 3 bars or atmospheres of pressure at a depth of 20 meters and 4 bar/atm at 30m.
Depth Bar/atmospheres (ATM) of pressure Volume of air in our bodies
0 meters (surface) 1 1
10 meters 2 1/2
20 meters 3 1/3
30 meters 4 1/4
