Question

At sea level the atmospheric pressure is (blank)  atm (or 101,325 kPa). For every 33 feet a diver goes deeper into the ocean 1 atm of pressure is added. If the wreck of the SS Atlas was at a depth of 80 feet, all divers were exploring it at a pressure of (blank)  atm.

Answer 1

The pressure at sea level is 1 ATM.This is equal to 101.325 kPa. (it is not a comma, but a decimal point.)

It is given that for a change in height of 33 feet, the pressure change is 1 atm.

The depth of the divers is 80 feet.

So to find the extra pressure, we have to find how many 33 feets are there in 80 feet.

N = 80/33 = 2.424

So, excess pressure at this depth = 2.424*1 ATM = 2.424 ATM.

So, the actual pressure at this depth = pressure at sea level + pressure difference due to depth = 1 +2.424 = 3.424 ATM.
