xii PREFACE

When using any of the formulas in this book that may come from an indus-
try or regulatory code, the user is cautioned to consult the latest version of the
code. Formulas may be changed from one edition of code to the next. In a work
of this magnitude it is difficult to include the latest formulas from the numerous
constantly changing codes. Hence, the formulas given here are those current at
the time of publication of this book.
In a work this large it is possible that errors may occur. Hence, the author
will be grateful to any user of the book who detects an error and calls it to the
author’s attention. Just write the author in care of the publisher. The error will
be corrected in the next printing.
In addition, if a user believes that one or more important formulas have been
left out, the author will be happy to consider them for inclusion in the next edition
of the book. Again, just write to him in care of the publisher.
Tyler G. Hicks, P.E.
