ENERGY ENGINEERING- AN INTRODUCTION
Energy
is defined as the ability to cause changes. Thermodynamics can be
defined as the science of Energy.
The
term Energy is derived from the Greek word Energia. Energy means capacity for
doing work. We use energy practically for everything to do. For example, energy
is needed to do all types of work, to operate household gadgets and appliances,
to move people as well as goods from one place to the other, to run the
machines, etc. Energy is existing in various forms, viz., Potential Energy,
Kinetic Energy, Mechanical Energy, Heat Energy, Chemical Energy, Nuclear
Energy, Electrical Energy, etc. All forms of energy are inter-convertible by
appropriate processes.
The
term Thermodynamics is derived from the Greek words Therme (heat) and
Dynamics (power). This terminology is the proof of the early efforts to convert
heat into power. Today, the same name is broadly interpreted to include all
aspects of energy and energy transformations, including power generation,
refrigeration, etc.
