OBJECTIVE:
The student is introduced to the mechanics of fluids through a
thorough understanding of the
properties of the fluids, behaviour of fluids under static conditions.
The dynamics of fluids is
introduced through the control volume approach which gives an
integrated understanding of
the transport of mass, momentum and energy. 2. The applications of
the conservation laws to
a) flow measurements b) flow through pipes (both laminar and
turbulent) and c) forces on
vanes is studied.
