(a) What is the density of a woman who floats infreshwater with 4.00% of her volume above the surface?This could be measured by placing her in a tank with markson the side to measure how much water she displaces whenfloating and when held under water (briefly). (b) What percentof her volume is above the surface when she floats inseawater?
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.
(a) What is the density of a woman who floats in
freshwater with 4.00% of her volume above the surface?
This could be measured by placing her in a tank with marks
on the side to measure how much water she displaces when
floating and when held under water (briefly). (b) What percent
of her volume is above the surface when she floats in
seawater?
