The book "Heat and Mass Transfer" by E. R. G. Eckert and Robert M. Drake, Jr. is reviewed by H. H. Sozin. The second edition, nearly doubled in content, is divided into five parts: conduction, convection, radiation properties and heat exchange, psychometrics and convective mass transfer, and steady-state and regenerative heat exchangers. Each part includes examples and problems, with references in footnotes. The book covers a wide range of topics, including special processes like aerodynamic heating and rarefied gases. While it lacks a comprehensive bibliography and some experimental techniques, it excels in its clear explanations and practical data. Despite some minor redundancies and omissions, the book is highly recommended for both students and engineers, offering a comprehensive understanding of the physical processes involved in heat and mass transfer.The book "Heat and Mass Transfer" by E.
