Question

Ali spot a large octopus while diving 40 meters deep in the pacific ocean sea. Given the density of the sea water and the atmosphere pressure is 1025 kg/m^3 and 101.325 kPa

a.) Calculate the pressure exerted on Ali's body.

b.) Calculate the absolute pressure exerted on Ali's body.

Answer 1

a) The pressure is

$$p=\rho gh=401800\text{ Pa}.$$

b) The pressure:

$$p_a=p+p_0=401800+101325=503125\text{ Pa}.$$
