hello friends we are starting with a new
subject today the name of the subject is
fluid mechanics now what is fluid
mechanics see fluid mechanics it is a
branch of science which deals with the
behavior of fluids so here I can mention
that fluid mechanics is the branch of
science which deals with behavior of
fluids and fluids they can be gases or
liquids so from the definition part it
is clear that fluid mechanics is the
branch of science which deals with the
behavior of fluids that is gases or
liquids it means how some fluids behave
because when we say fluid we mean that
gases or liquids it means fluid does not
mean that they should only be liquid
gases can also be treated as fluids so
when we are studying the behavior of
gases or liquids that study is called as
fluid mechanics now in fluid mechanics
we can say that fluid mechanics it
consists of
normally fluid mechanics it is divided
into three parts
those are number one fluid statics
second fluid kinematics and the third
one fluid dynamics so here we have three
different parts of fluid mechanics fluid
statics first part fluid kinematics the
second part and fluid dynamics the third
part now when we are talking about fluid
statics fluid statics it is the study of
fluids at rest so whenever we are
studying a fluid which is at rest it
means it becomes fluid statics that is a
branch of fluid mechanics next fluid
kinematics it is the study of fluids in
motion neglecting
pressure forces that is if we are
studying the fluids which are in motion
and neglecting the pressure forces then
it becomes fluid kinematics and the last
part that is fluid dynamics it is the
study of fluids in motion considering
the pressure forces so here we have seen
that what is fluid mechanics it is a
branch of science which deals with the
behavior of fluids and fluid does not
mean only liquid fluid they can be
liquids as well as gases so the branch
of science which deals with the study of
the fluids or the behavior of fluids
that is called as fluid mechanics and
fluid mechanics it is divided into three
parts fluid statics fluid kinematics and
fluid dynamics in fluid statics we are
studying the behavior of fluids which
are at rest in fluid kinematics we are
studying the behavior of fluids which
are in motion and neglecting the
pressure forces in case of fluid
dynamics we are studying the behavior of
fluids which are in motion and we are
considering the pressure forces here so
in short this video gave us a brief
overview of fluid mechanics with its
types
