A scuba diver is experiencing a pressure of 5.0 atm. to what depth in feet has he dived? careful, remember that just by being on the surface of the sea he is at 1.0 atm! it might be useful to remember that: the density of mercury is 13.6 g/ml, the density of water is 1.00 g/ml and that there are 3.28 ft in one meter.

Since the surface of the sea is already at 1 atm therefore the pressure due to hydraulics is 4 atm.

We know that hydraulic pressure is:

P = ρ g h

where ρ is density, g is gravity and h is height

P = 1000 kg/m^3 * 9.81 m/s^2 * h = 4 atm * 101325 Pa / atm

h = 41.34 m = 135.5 feet
