9th enlarged and revised edition
The purpose of this collection of
technical formulae is to provide a brief, clear and handy guide to the
more important technical and mathematical formulae.
Since the book has
been printed on one side of the page only, the facing pages are available
for additional notes.
Each separate subject has been associated with a
capital letter. The various formulae have been grouped under corresponding
small letters and numbered serially. This method enables the formulae used
in any particular calculation to be indicated.
The section HEAT has
been by the application HVAC (heat, ventilation, air condition), in which
many tables with thumb values are included.
