Fundamentals of Fluid Mechanics
SCOPE OF FLUID MECHANICS
Knowledge and understanding of the basic principles and concepts of fluid mechanics are
essential to analyze any system in which a fluid is the working medium. The design of almost
all means transportation requires application of fluid Mechanics. Air craft for subsonic and
supersonic flight, ground effect machines, hovercraft, vertical takeoff and landing requiring
minimum runway length, surface ships, submarines and automobiles requires the knowledge
of fluid mechanics. In recent years automobile industries have given more importance to
aerodynamic design. The collapse of the Tacoma Narrows Bridge in 1940 is evidence of the
possible consequences of neglecting the basic principles fluid mechanics.
The design of all types of fluid machinery including pumps, fans, blowers,
compressors and turbines clearly require knowledge of basic principles fluid mechanics.
Other applications include design of lubricating systems, heating and ventilating of private
homes, large office buildings, shopping malls and design of pipeline systems.
The list of applications of principles of fluid mechanics may include many more. The
main point is that the fluid mechanics subject is not studied for pure academic interest but
requires considerable academic interest.
