I just "published" an e-book, "Advanced Chemical Reactor Modeling (with Mathcad): Single Phase Fluid". It is available on my website, www.harveyhensley.com. There is plenty of description about the book on the website, including the links to the Preface, Table of Contents, and the Introduction. The book is available in both pdf and xmcd formats. They are identical, so if you purchase, you only need one version. Any feedback, either on my website or here will be welcome.
