The purpose of this book is to provide an introduction to the several rate equations and techniques for determining the rate of heat transfer across system boundaries in a variety of settings. We hope that self-study students and working engineers alike will find it useful as a resource. Learning involves asking and answering one’s own questions, whether one is studying alone or in a group setting. We’re hoping this book can help make it happen. Using clear and accessible language, Heat and Mass Transfer covers a wide range of subjects fundamental to the fields of energy studies and mass transfer. Research, examples, and other exercises are used extensively throughout the text to illustrate key concepts.
