ABSTRACT
Fluid mechanics is one of the most important lessons taught in most
engineering departments because fluoride mechanics are a vital part of
life without which we cannot live. And each and every one has its own
work. In physics and engineering, fluid dynamics (subdiscribes) in
mechanical fluid refers to the flow of fluid with gases. There are several
subdiscribers, the dynamics of the air include the study of air and other
gases in motion with (fluid science) which is also the study of fluids in
motion, the motion of fluids also has a wide range of uses. Such as the
analysis of the force and force of the plane, determining the mass flow
rate of oil along the pipeline, predicting the type of weather,
understanding the velocity of a single cloud in the star space with the
shape of the pieces of the explosive weapon.
The fluid movement is the presentation of the structure of the system that
falls under the act of parameter - that is, the law of experiential
satisfaction and semi-experimental design. Used in flow measurements to
analyze questions, the solution to the fluid motion questions involves
participating in the calculation of various fluid properties such as flow
velocity, pressure, density, and temperature, such as time and space maps.
Prior to the twentieth century the science of fluid forces accorded with
fluid motion that is still fragmented within some fluid motion subjects
such as magnetic hydrodynamics and alternative hydrodynamics, both of
which can be applied to gases.

INTRODUCTION
Fluid Mechanics is the study of fluids at rest (fluid statics) and in motion
(fluid dynamics).
A fluid is defined as a substance that continually deforms (flows) under
an applied shear stress regardless of the magnitude of the applied stress.
Whereas a solid can resist an applied force by static deformation.
Liquids,Gases,Plasmas, and, to some extent, plastic solids are accepted to
be fluids. A perfect fluid offers no internal resistance to change in shape
and, consequently, they take on the shape of their containers. Liquids
form a free surface (that is, a surface not created by their container)
whereas gases and plasmas do not, but, instead, they expand and occupy
the entire volume of the container.

I thought about how beautiful a flagfell it
looks when it waves. I realized that the the
wind blowing on the flag actually
produces a drag force on the flag. This
force acts on both sides of the flag. This
drag is due to the wind blowing over the
side of the flag. Thus the force itself is
actually the shear force acting on the flag.

Solution:
T (F) = 1.8 T (C°) +32
100 - 32 = 1.8 T C°
68 = 1.8 T C°
T = 37.77 C°
T (K) = T(C°) +273.15
T(K) = 37.77 C°+ 273.15
T = 310.92 K

CONCLUSION
In my report generally I talked about the benefities of fluid mechanics in
our lifes and in our studies such as that Enginnering , we get that
information that Fluid mechanics is basic way in our life we see it we use
it it's urgency for humanity without it life couldn't be regulary. So that
Mr.Mahdi in this report ask me a question about changing the
temperature he give me 100 F I change to Celsius and Kelvin. In that
Report I know that the fluid Mechanics is very important things that
everyone must know about it to be solve the life problems easier.
