As the most comprehensive reference and study guide available for engineers preparing for the breadth-and-depth mechanical PE examination, the twelfth edition of the "Mechanical Engineering Reference Manual "provides a concentrated review of the exam topics. Thousands of important equations and methods are shown and explained throughout the "Reference Manual," plus hundreds of examples with detailed solutions demonstrate how to use these equations to correctly solve problems on the mechanical PE exam. Dozens of key charts, tables, and graphs, including updated steam tables and two new charts of LMTD heat exchanger correction factors, make it possible to work most exam problems using the "Reference Manual" alone. A complete, easy-to-use index saves you valuable time during the exam as it helps you quickly locate important information needed to solve problems.
