At a depth of 10.9 km, the Challenger Deep in the Marianas Trench of the Pacific Ocean is the deepest site in any ocean. Yet, in 1960, Donald Walsh and Jacques Piccard reached the Challenger Deep in the bathyscaph Trieste. Assuming that seawater has a uniform density of 1024 kg/m3, approximate the hydrostatic pressure (in atmospheres) that the Trieste had to withstand.

Answer :

Answer:

[tex]P = 1.09 \times 10^8 Pa[/tex]

Explanation:

As we know that the pressure inside the liquid level is given as

[tex]P = \rho g h + P_o[/tex]

here we have

[tex]\rho = 1024 kg/m^3[/tex]

h = 10.9 km

also we know that

[tex]P_o = 1.01 \times 10^5 Pa[/tex]

now we have

[tex]P = (1.01 \times 10^5) + (1024)(9.81)(10.9 \times 10^3)[/tex]

[tex]P = 1.09 \times 10^8 Pa[/tex]
