Application Areas of Fluid Mechanics
Pipeline: The piping systems for water, natural gas, and sewage for
an individual house and the entire city are designed primarily on the
basis of fluid mechanics.
Piping and ducting network of heating and air-conditioning systems.
Automobile: All components associated with the transportation of
the fuel from the fuel tank to the cylinders—the fuel line, fuel
pump, and fuel injectors or carburetors—as well as the mixing of the
fuel and the air in the cylinders and the purging of combustion gases
in exhaust pipes—are analyzed using fluid mechanics.
Fluid mechanics is also used in the design of the heating and airconditioning system, the hydraulic brakes, the power steering, the
automatic transmission, the lubrication systems, the cooling system
of the engine block including the radiator and the water pump, and
even the tires.
On a broader scale, fluid mechanics plays a major part in the design
and analysis of aircraft, boats, submarines, rockets, jet engines, wind
turbines, biomedical devices, cooling systems for electronic
components, and transportation systems for moving water, crude
oil, and natural gas.

Introduction
Mechanics applies to material bodies in the solid phase, the discipline
is called solid mechanics.
When the material body is in the gas or liquid phase, the discipline is
called fluid mechanics.
In contrast to a solid, a fluid is a substance whose molecules move
freely past each other.
Fluid is a substance that will continuously deform—that is, flow under
the action of a shear stress.
Solid will deform under the action of a shear stress but will not flow
like a fluid.
Both liquids and gases are classified as fluids.
Fluid Mechanics is the science that deals with the behavior of fluids
at rest or in motion, and the interaction of fluids with solids or other
fluids at the boundaries.
