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. For heat transport phenomena, we want to go beyond study and establish a tangible understanding. More than that, we want to show how this concept applies to the surrounding world. Our goal is to encourage research that provides deeper understanding of heat transfer events than can be gained from simple thermal behaviour descriptions. 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.
