It is the best book money can buy on this subject. I reccommend this book first before consulting to any Heat , Mass Transfer or Diffusion books.<br>But, the dear author is a techer who has an Electric &amp; Electronic Engineereing background I guess. According to my opinion, it would be more attractive, practical and useful for wider engineering fields if this valuable book could have contained more samples or excersises regarding with Heat and/or Mass transfer and Strength for chemical and mechanical engineering students and engineers.
