# Fundamentals of Heat and Mass Transfer, 7th Edition

## Description

Fundamentals of Heat and Mass Transfer, 7th Edition is the gold standard of heat transfer pedagogy for more than 30 years, with a commitment to continuous improvement by four authors having more than 150 years of combined experience in heat transfer education, research and practice. Using a rigorous and systematic problem-solving methodology pioneered by this text, it is abundantly filled with examples and problems that reveal the richness and beauty of the discipline. This edition maintains its foundation in the four central learning objectives for students and also makes heat and mass transfer more approachable with an additional emphasis on the fundamental concepts, as well as highlighting the relevance of those ideas with exciting applications to the most critical issues of today and the coming decades: energy and the environment. An updated version of Interactive Heat Transfer (IHT) software makes it even easier to efficiently and accurately solve problems.

• The definitive text on Heat and Mass Transfer, this book continues to be built around the four central learning objectives, including:
1. The reader should internalize the meaning of the terminology and physical principles associated with heat transfer.
2. The reader should be able to delineate pertinent transport phenomena for any process or system involving heat transfer.
3. The reader should be able to use requisite inputs for computing heat transfer rates and/or material temperatures.
4. The reader should be able to develop representative models of real processes and systems and draw conclusions concerning process/system design or performance from the attendant analysis.
• Teaches students the rigorous and systematic problem-solving methodology developed and honed by the Incropera author team
• A wealth of example problems to better show how to apply the material across various engineering disciplines and fields
• Identifies problems that are uniquely suited for solving with a computational software tool, both to increase efficiency and to decrease errors
