Heat Transfer has been written for undergraduate students in mechanical, nuclear, and chemical engineering programs. The success of Anthony Mill's Basic Heat and Mass Transfer and Heat Transfer continues with two new editions for 1999. The careful ordering of topics in each chapter leads students gradually from introductory concepts to advanced material, eliminating road blocks to developing solid engineering problem-solving skills. Mathematical concepts, from earlier courses, are reviewed on as needed basis refreshing students' memories, and the computational software integrated with the text allows them to obtain reliable numerical results. The integrated coverage of design principles and the wide variety of exercises based on current heat and mass transfer technologies encourages students to think like engineers, better preparing them for the engineering workplace.
