Heat Transfer E- Book
Energy is
defined as the capacity of a substance to do work. It is a property of the
substance and it can be transferred by interaction of a system and its
surroundings. The student would have encountered these interactions during the
study of Thermodynamics. However, Thermodynamics deals with the end states of
the processes and provides no information on the physical mechanisms that
caused the process to take place. Heat Transfer is an example of such a
process. A convenient definition of heat transfer is energy in transition due
to temperature differences. Heat transfer extends the Thermodynamic analysis by
studying the fundamental processes and modes of heat transfer through the
development of relations used to calculate its rate.
The aim of
this chapter is to console existing understanding and to familiarise the
student with the standard of notation and terminology used in this book. It
will also introduce the necessary units.

Engineering Thermodynamics E- Book
Thermodynamics
is an essential subject taught to all science and engineering students. If the
coverage of this subject is restricted to theoretical analysis, student will
resort to memorising the facts in order to pass the examination. Therefore,
this book is set out with the aim to present this subject from an angle of
demonstration of how these laws are used in practical situation.
This book is
designed for the virtual reader in mind, it is concise and easy to read, yet it
presents all the basic laws of thermodynamics in a simplistic and
straightforward manner. The book deals with all four laws, the zeroth law and
its application to temperature measurements. The first law of thermodynamics
has large influence on so many applications around us, transport such as automotive,
marine or aircrafts all rely on the steady flow energy equation which is a
consequence of the first law of thermodynamics. The second law focuses on the
irreversibilities of substances undergoing practical processes. It defines
process efficiency and isentropic changes associated with frictional losses and
thermal losses during the processes involved.

Engineering Fluid Mechanics E- Book
Fluid
A fluid is a
substance, which deforms when subjected to a force. A fluid can offer no
permanent resistance to any force causing change of shape. Fluid flow under
their own weight and take the shape of any solid body with which they are in
contact. Fluids may be divided into liquids and gases. Liquids occupy definite
volumes. Gases will expand to occupy any containing vessel.
S.I Units in
Fluids
The
dimensional unit convention adopted in this course is the System International
or S.I system. In this convention, there are 9 basic dimensions. The three
applicable to this unit are: mass, length and time.
The
corresponding units are kilogrammes (mass), metres (length), and seconds
(time). All other fluid units may be derived from these.

CAD-CAM & Rapid Prototyping Application Evaluation E- Book
CAD-CAM
systems are probably the most significant development in the field of new
technology related to engineering, design and drafting in all technical
spheres. These systems find application in all branches of modern design – from
machine engineering and microelectronics to architecture and construction
building and others. In current publication the author describes in detail via
review, analysis and processing case study data the state of art in the
selection, application and implementation of such systems. The past decade has
additionally witnessed the emergence of new manufacturing technologies that
build parts on a layer-by-layer basis. Using these technologies, manufacturing
time for parts of virtually any complexity is measured in hours instead of
days, weeks, or months. In other words, it is rapid. A host of related
technologies that are used to fabricate physical objects directly from
Computer-Aided Design data sources are reviewed in the last chapter. These
methods are generally similar to each other in that they add and bond materials
in layerwise-fashion to form objects.
