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

SP5. A pipe with a circular cross section has a diameter of 9 cm.
It narrows at one point to a diameter of 5.2 cm. The pipe is
carrying a steady stream of water that completely fills the
pipe and is moving with a speed of 1.6 m/s in the wider
portion.
a. What are the cross-sectional areas of the wide and nar-
row portions of the pipe? (A = ar", and the radius is half
the diameter.)
b. What is the speed of the water in the narrow portion of
the pipe?
c. Is the pressure in the narrow portion of the pipe greater
than, less than, or equal to the pressure in the wider
portion? Explain.

Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g (the bone is water light) a. What mass of water is displaced? b. What is the volume of the bone? c. What is its average density?
