PREFACE TO THE SECOND EDITION
While the main skeleton of the first edition is preserved, Chapters 10 and 11 have been rewrit-
ten and expanded in this new edition. The number of example problems in Chapters 8–11 has
been increased to help students to get a better grasp of the basic concepts. Many new prob-
lems have been added, showing step-by-step solution procedures. The concept of time scales
and their role in attributing a physical significance to dimensionless numbers are introduced
in Chapter 3.
Several of my colleagues and students helped me in the preparation of this new edition.
I thank particularly Dr. Ufuk Bakır, Dr. Ahmet N. Eraslan, Dr. Yusuf Uludag,˘ and Meriç
Dalgıç for their ments and suggestions. I extend my thanks to Russell Fraser for
reading the whole manuscript and improving its English.

PREFACE TO THE FIRST EDITION
During their undergraduate education, students take various courses on fluid flow, heat trans-
fer, mass transfer, chemical reaction engineering, and thermodynamics. Most of them, how-
ever, are unable to understand the links between the concepts covered in these courses and
have difficulty in formulating equations, even of the simplest nature. This is a typical example
of not seeing the forest for the trees.
The pathway from the real problem to the mathematical problem has two stages: perception
and formulation. The difficulties encountered at both of these stages can be easily resolved if
students recognize the forest first. Examination of the trees one by es at a later stage.
In science and engineering, the forest is represented by the basic concepts, ., conser
