Fluid mechanics is the branch of physics concerned with the mechanics of liquids and gases at rest or in motion. It encompasses a wide range of problems involving blood flow in capillaries to crude oil flow through pipelines. Fluid mechanics principles are used to explain airplane aerodynamics and golf ball designs. Computational fluid dynamics uses computer simulations and software like ANSYS and MATLAB to model and study fluid flow problems. Fluid mechanics has many applications in areas like aviation, vehicles, turbines, hydraulics, and renewable energy technologies. The future of fluid mechanics includes further research in renewable energy and nanofluids.

4.  How can a rocket generate thrust without having any air to push against in outer space?
 Why can’t you hear a supersonic airplane until it has gone past you?
 How can a river flow downstream with a significant velocity even though the slope of the
surface is so small that it could not be detected with an ordinary level?
 How can information obtained from model airplanes be used to design the real thing?
 Why does a stream of water from a faucet sometimes appear to have a smooth surface, but
sometimes a rough surface?

6. FLUID STATICS
the fluid is either at rest or moving in
such a manner that there is no
relative motion between adjacent
particles. In both instances there will
be no shearing stresses in the fluid
,and the only forces that develop on
the surfaces of the particles will be
due to the pressure. Thus,our
principal concern is to investigate
pressure and its variation throughout
a fluid and the effect of pressure on
submerged surfaces.

7. Nasa space rocket – Atlas and orbiter
In general, fluids have a well-
known tendency to move or flow.
It is very difficult to “tie down” a
fluid and restrain it from moving.
The slightest of shear stresses
will cause the fluid to move.
Similarly, an appropriate
imbalance of normal stresses
pressure will cause fluid motion.
This include velocity field ,
pressure field , Bernoulli
equation and boundary
conditions as well fluid
