Calculate the pressure due to the ocean at the bottom ofthe Marianas Trench near the Philippines, given its depth is11.0 km and assuming the density of sea water is constantall the way down. (b) Calculate the percent decrease involume of sea water due to such a pressure, assuming itsbulk modulus is the same as water and is constant. (c) Whatwould be the percent increase in its density? Is theassumption of constant density valid? Will the actual pressurebe greater or smaller than that calculated under thisassumption?
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.
Calculate the pressure due to the ocean at the bottom of
the Marianas Trench near the Philippines, given its depth is
11.0 km and assuming the density of sea water is constant
all the way down. (b) Calculate the percent decrease in
volume of sea water due to such a pressure, assuming its
bulk modulus is the same as water and is constant. (c) What
would be the percent increase in its density? Is the
assumption of constant density valid? Will the actual pressure
be greater or smaller than that calculated under this
assumption?
