Learning Objectives<br />
After completing this chapter, you should be able to:<br />
■ determine the dimensions and units of physical quantities.<br />
■ identify the key <strong>fluid</strong> properties used in the analysis of <strong>fluid</strong> behavior.<br />
■ calculate common <strong>fluid</strong> properties given appropriate information.<br />
■ explain effects of <strong>fluid</strong> compressibility.<br />
■ use the concepts of viscosity, vapor pressure, and surface tension.<br />
Fluid <strong>mechanics</strong> is that discipline within the broad field of applied <strong>mechanics</strong> that is concerned<br />
with the behavior of liquids and gases at rest or in motion. It covers a vast array of phenomena<br />
that occur in nature (with or without human intervention), in biology, and in numerous engineered,<br />
invented, or manufactured situations. There are few aspects of our lives that do not involve <strong>fluid</strong>s,<br />
either directly or indirectly.<br />
