Question

Question:

A submarine dives to a depth of 120 meters in the ocean. What is the force (in Newtons) acting on a hatch that has an area of 5.00 square meters? 

Answer 1

Step 1

Let's determine the hydrostatic pressure.

P = ρ g h

P = 1035(9.81)120 = 1 218 402 N/m²

 

Step 2

 

Let's determine the force exerted on the hatch.

F =P*A

F = 1 218 402 N/m²  (5.00 m²) = 6 092 010 N

= \( \boxed{\rm 6.09\times{10^{6}}\ N} \)

 

The force on the hatch of about   \( \rm 6.09\times{10^{6}}\ N \)
