Incropera's Fundamentals of Heat and Mass Transfer has been the gold standard of heat transfer pedagogy for many decades, with a commitment to continuous improvement by four authors’ with more than 150 years of combined experience in heat transfer education, research and practice. Applying the rigorous and systematic problem-solving methodology that this text pioneered an abundance of examples and problems reveal the richness and beauty of the discipline. This edition makes heat and mass transfer more approachable by giving additional emphasis to fundamental concepts, while highlighting the relevance of two of today’s most critical issues: energy and the environment.
