Description

Written for chemical, mechanical, and aerospace engineering students taking courses on heat and mass transfer, this textbook presents the basics and proceeds to the required theory and its application aspects. Major topics covered include conduction, convection, radiation, boiling, heat exchangers, and mass transfer and are explained in a detailed, to-the-point manner. Along with coverage of the topics, the author provides appropriate numerical examples to clarify theory and concepts. Exercise problems are presented at the end of each chapter to test the understanding gained within each subject. A solutions manual and PowerPoint slides accompany the text, upon qualification.
