Answer to Question #170667 in Mechanics | Relativity for Paulo

Question

what is the pressure 12.5m below the ocean? Use the sp. gr. = 1.03 for salt water.

Answer 1

The gauge pressure at any depth is given by,

P_g = ρgh

The atmospheric pressure:

$P_0 = 1.013 \times 10^5 \;Pa$

The pressure at this depth will be:

$P = P_0 + P_g \\ = 1.013 \times 10^5 + 1.03 \times 10^3 \times 9.8 \times 12.5 \\ = 2.27 \times 10^5 \;Pa$
