Concept explainers

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.

Question

An aquatic organism needs to be neutrally buoyant
to stay at a constant depth. Fish accomplish this
with an internal swim bladder they can fill with air
that they take in from the water through their gills.
One complication is that the pressure in the swim
bladder matches that of the surrounding water, but
the water pressure changes with depth. Because
the volume of a gas is inversely proportional to
pressure (as you may already know if you have
studied the ideal-gas law), the volume of air in a
fish's swim bladder decreases with depth unless
the fish actively adds more air.

Part C
What volume of air would have to be added to the swim bladder for the fish to remain neutrally buoyant at a depth of
20 m?
Express your answer in milliliters to two significant figures.
