Answer #1

We can consider the pressure exerted by air as the atmospheric pressure, that is: 1 Atm of 101325 Pa.

To this, we have to add the pressure of the 100 m of water above the subject. The pressure from a column of liquid is given by.

Where ρ is the density of the water, g is the acceleration of gravity and h is the height of water. In our case:

So the total pressure is:
