will also find the book useful. The advanced user will need to progress to specialized text books
and the standard references.
The reader is challenged to become actively engaged in the design calculations carried out
by design engineers, through step-by-step introduction of each stage. A standard of numerical
competence is expected that some lecturers may consider being higher than is necessary for some
courses. This was deemed appropriate in order to broaden the potential readership and provide
an adequate basis for a deeper design study.
Readers are encouraged to make use of the internet as a learning resource. Graphics included
in a printed book are there to explain a basic principle. Use a search engine to view real plant
items such as steel panel heating radiators, pumps, air-handling units, fire extinguishers or lifts,
as needed. For example, a search for Wartsila takes the enquirer straight to the manufacturer of
the geothermal heating CHP equipment. Happy surfing!
