3. 3. OUTLINE  Introduction  Types of flow  Applications of Fluid Mechanics
4. 4. Introduction to Fluid Mechanics  Fluid Mechanics - A section of applied mechanics, concerned with the static and dynamics of liquid and gases.  Deals with the study of the motion of general behavior of a fluid governed by the law of conversation of mass, laws of mechanics and of thermodynamics.
5. 5. Introduction  Fluid mechanics has its wide range of application and science everywhere there’s flow of fluid.  Pumps, Storage tanks , water & waste water treatment plant, sewer network, water supply network, dams, car-bikes-plane-boats, biogas plants, tornado-tsunami mitigation equipments, various treatments for human or any living body, various outer space phenomenon etc. are all due to various science of fluid flow.
6. 6. Reynold’s Experiment  To design any applied phenomenon, fundamental properties like density ,pressure ,velocity etc. are taken as basic unit parameters for deciding type of flow.  Reynold’s Experiment is one such application for describing type of flow in fluid kinematics which is governed by following equation.  Re < 2000 for laminar flow  2000 < Re < 4000 for transition flow  Re > 4000 for turbulent flow

8. 8. Applications of Fluid Mechanics  Though applications of Bernoulli's principle are among the most dramatic examples of fluid mechanics in operation, the everyday world is filled with instances of other ideas at work. Pascal's principle, for instance, can be seen in the operation of any number of machines that represent variations on the idea of a hydraulic press. Among these is the hydraulic jack used to raise a car off the floor of an auto mechanic's shop.
9. 9. Bernoulli's Principle in Action  As fluid moves from a wider pipe to a narrower one, the volume of the fluid that moves a given distance in a given time period does not change. But since the width of the narrower pipe is smaller, the fluid must move faster (that is, with greater dynamic pressure) in order to move the same amount of fluid the same distance in the same amount of time. Observe the behavior of a river: in a wide, unconstricted region, it flows slowly, but if its flow is narrowed by canyon walls, it speeds up dramatically.

13. 13.  Among the most famous applications of Bernoulli's principle is its use in aerodynamics, and this is discussed in the context of aerodynamics itself elsewhere in this book. Likewise, a number of other applications of Bernoulli's principle are examined in an essay devoted to that topic.
14. 14. A Wind Tunnel  The above scenario of wind flowing through a room describes a rudimentary wind tunnel. A wind tunnel is a chamber built for the purpose of examining the characteristics of airflow in contact with solid objects, such as aircraft and automobiles.

16. 16. Hair Dryer  Many girls we know blow dry their hair on a regular basis. Like them, we enjoy this commodity of everyday life. if we center the blow dryer above our head and point down, we can feel the shear force of the air blowing over our face and hair. 17
17. 17.  A pump is a device made for moving fluid, and it does so by utilizing a pressure difference, causing the fluid to move from an area of higher pressure to one of lower pressure. Its operation is based on aspects both of Pascal's and Bernoulli's principles—though, of course, humans were using pumps thousands of years before either man was born.

22. 22. Surface Tension : “ Surface tension is the elastic tendency of liquids that makes them acquire the least surface area possible. Surface tension causes insects usually denser than water to float and stride on the water surface ”
