Hofisaib is a doctor aboard a US Navy nuclear submarine, and is currently off the Coast of Hong Kong to assist refugees attempting to flee the city. If the pressure of the water outside of Jonathan's submarine is 25 atm, how deep is Hofisaib's submarine below the ocean surface? [the density of sea water is 1,025 kg/m^3]
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
