1. What important property of fluids necessitated the develop-
ment of fluid mechanics as an area of science separate from
standard mechanics?
2. How is pressure calculated? How does pressure change when
each of its contributing factors is increased?
3. How does pressure exerted by a solid object on a surface differ
from pressure exerted within a liquid or a gas?
4. What is the derived unit of pressure in the SI? To what combi-
nation of SI units is it equal? What pressure unit is used in
weather prediction?
5. Discuss the difference between gauge pressure and absolute
pressure. What is a gauge pressure of zero equivalent to?
6. What two factors affect the pressure in a fluid? How does grav-
ity affect each of these? What two aspects of a fluid container
do not affect fluid pressure?
7. State Archimedes's principle in your own words.
8. List the three kinds of buoyancy by comparing the densities of
the fluid and the object in the fluid. Describe what happens to
the object in each case.
9. Why is specific gravity useful?
10. (True or False) If a mercury barometer were taken into a deep
mine on a typical day, the mercury column would probably be
taller than 760 mm
