The basic fundamentals of fluid mechanics are essential for understanding the fluid dynamics of pumping machinery. This chapter aims to provide a quick revision of the definitions and basic laws of fluid dynamics that are important for a thorough understanding of the material presented in this book. Of particular interest are the kinematics of fluid flow; the three conservation principles of mass, momentum, and energy; relevant dimensionless parameters; laminar and turbulent flows; and friction losses in piping systems. Some applications of relevance to pumping machinery are also considered.
1.1 Kinematics of Fluid Flow
To fully describe the fluid motion in a flow field it is necessary to know the flow velocity and acceleration of fluid particles at every point in the field. This may be a simple task in laminar flows but may be difficult in turbulent flows. If we use the Eulerian method and utilize Cartesian coordinates, the velocity vector at any point in a flow field can be expressed as
(1.1)
where
is the velocity vector; u, v, and w are the velocity components in the x, y, and z directions; and
, and
are unit vectors in the respective directions. In general, each of the velocity components can be a function of position and time, and accordingly we can write
(1.2)
The components of acceleration in the three directions can be expressed as
(1.3a)
(1.3b)
(1.3c)
The acceleration vector becomes
(1.4)
This vector can be split into two components, the local component,
, and the convective component,
, that can be expressed as
