From the Preface...
The first edition was published in 1995 and a revised reprint in 2008. It has been noted that with some changes it could be significantly improved. This second edition is the result of such changes.
The major improvement is the addition of the mass transfer supplement by Professor Sameer Dalvi. With this addition, the book can be used in all the schools whether the mass transfer is taught or not.
Some of the materials have been rearranged. The general one-dimensional conduction equation with the variable area of cross section is introduced earlier in chapter 2 and its applications to several problems along with the derivation of the equations from first principles are illustrated through several examples. Similarly, in the chapter on Heat Exchangers, both the NTU and LMTD methods of analysis are first presented, followed by
the solution of several problems using both methods in each. Some explanations have been made more compact and some rewritten. Several figures and materials considered unnecessary for an understanding of the subject have been deleted. Convective heat transfer coefficient has been replaced by the surface heat transfer coefficient where appropriate. A section on heat transfer with jet impingement is added. Properties of
several materials have been updated. Updated references (appendices 2 through 7), which are used infrequently have been shifted to the accompanying CD.
To the faculty teaching heat transfer: I believe the book has sufficient material for two courses, an introductory course, and an advanced course. In the introductory course, it is recommended that the material in chapters 1, 2, 4, 6, 7, and 9 be presented. Time permitting chapter 10 on Multimode Heat Transfer, and those sections of interest to the faculty in chapters 3, 5, and 8 may be included in the first course. In the second course, the remaining topics and material in chapters 3, 5, 8, 10, 11, and 12 may be presented. The solutions to many example problems start with conceptual solutions (with a gray background). Those solutions are roadmaps for the solutions. I hope the instructors find the conceptual solutions important enough to impress on the students that they should also begin the solutions to assigned problems with similar conceptual solution.
To the students: I have endeavored to make the text student-centric. In the example problems, all concepts have been explained in detail. I strongly recommend that the students begin the solutions to assigned problems with a conceptual solution. Examples of such conceptual solutions to many example problems can be found with a gray background. With all the improvements I hope the instructors and students will find the book more useful.
