Question

When scuba diving, you must equalize the pressure inside your body with the water outside every few meters you dive downward or swim upwards in order to avoid serious health complications. Calculate how far underwater you must dive in order to feel an extra atmosphere's worth of pressure around you. The density of water is 1000 kg/m3. meters Recreational divers rarely go deeper than about 130 ft deep. About how many extra atmospheres of pressure do they feel at this point? (Round to the nearest whole number). atmospheres

Explanation / Answer

P = gh

= 1000 x 9.8 x 130 x 0.3048

= 388315.2 Pascals

1 atm = 101325 Pascals

Extra Atmospheric pressure :

388315.2/101325 = 3.83 atm
