This third edition of the bestselling textbook presents a systematic treatment of the selection, rating, and thermal-hydraulic design of various types of heat-exchanging equipment. Explaining the fundamentals of the design method, the authors include more than 40 solved examples to illustrate their assertions regarding design and rating of heat exchangers. In addition, every chapter now includes thermal design problems that graduating undergraduate students can use in selecting capstone design projects. The book includes a new chapter on micro-heat exchangers and a revised solution manual, which is available with qualifying adoption.
