1.
The hydrostatic pressure exerted by a static homogeneous liquid of density rho at depth h beneath its free surface is expressed by:
P = rho * h / g
P = rho * g / h
P = rho * g * h
P = 1/2 rho * g * h2
2.
A diver descends to a depth of 30 meters in seawater (density = 1030 kg/m3. If atmospheric pressure is 1.013 x 105 Pa and g = 9.8 m/s2, the total absolute pressure experienced by the diver is approximately:
3.03 x 105 Pa
6.06 x 105 Pa
1.01 x 105 Pa
4.04 x 105 Pa (approx. 4.0 atmospheres)
