Assuming atmospheric pressure to be 1.01 x 10^5 pa and the density of sea water to be 1025 kg/m^3, what is the absolute pressure at a depth of 15.0 m below the surface of the ocean?

To solve for absolute pressure, you will need this formula:



Where: = absolute pressure
              = atmospheric pressure
             r (rho) = density
             g  = acceleration due to gravity constant
             h = depth (in this case)

rgh is the formula for pressure of fluids

So with your given, we just need to insert it into the formula:


= 1.01 x x (1,025 x 9.8 x 15 m
= 1.01 x + 150,675
= 1.01 x + 1.51 x

= 2.52 x This is your absolute pressure.
