ME2204 FLUID MECHANICS
AND MACHINERY LTPC
(Common to Aeronautical, Mechanical, Automobile &
Production) 3104
OBJECTIVES:
The student is introduced to the
mechanics of fluids through a thorough understanding of
the properties of
the fluids. The dynamics of fluids is introduced through the control volume
approach which gives an integrated under standing of the transport of mass, momentum and
energy.
The applications of the conservation
laws to flow though pipes and hydraulics machines
are studied
UNIT I INTRODUCTION 12
Units &
Dimensions. Properties of fluids - Specific gravity, specific weight,
viscosity,
compressibility, vapour pressure and
gas laws - capillarity and surface tension. Flow
characteristics: concepts of system
and control volume. Application of control volume to
continuity equiation, energy equation,
momentum equation and moment of momentum equation.
UNIT II
