Fundamentals of Momentum, Heat, and Mass Transfer, now in its sixth edition, continues to provide a unified treatment of momentum transfer (fluid mechanics), heat transfer, and mass transfer. This new edition has been updated to include more coverage of modern topics and new applications, such as macro- and micro-scale chemical reactors. Additionally, the sixth edition focuses on an explicit problem-solving methodology that is thoroughly and consistently implemented throughout the text. It is designed for undergraduates taking transport phenomena or transfer and rate process courses.
