I am a Junior/Senior in Chemical Engineering, and I can't say enough about this set I recently purchased. My husband is a Graduate student in Chemical Engineering and he told me to hold off, that he never used his copy (1991 version), and never needed it in college. I use the electronic book all the time on my laptop. It's a great resource, and so EASY to use. I even caught my husband using my Perry's on more than one occasion, and he finally admitted my version was much better and easier to use than his! He went out and bought his OWN copy! I pretty much only use the electronic book, but it's nice to know if my laptop crashed, I have a hardcopy to go to. With the active 8, you can get the variables from a z-Compressibility Chart without having to take out the magnifying lens and ruler. Just slide your mouse and a red bordered legend tells you the Tr Pr and z simultaneously until you reach your desired measurements. Printing is a cinch, and it looks like the hardcopy except on 1 page! As I said, I use this book about every day, and I am sure this is what I'll bring to the office when I'm done with school. This would have been sweet during my Material/Energy Balance class as a sophomore, too. If you're a student you already spend $500+ on textbooks a term anyway, you might as well buy a book that has the information of every book you will buy in college in one resource for a little extra money, I put my name on it. You won't regret it if you're serious about your major.

I am a chemical engineering student at Kansas University, where Don Green teaches. I just hope that when I take my econ. class from him next semester, that his class is as easy as this book is easy to use.....a must for students, not only professionals

I used the early editions of Perry before, but this 7th edition is the most comprehensive one ever. All you need from steam tables to equations & formulae are all included in the CD ROM. I recommend it to every professional engineer in power plant and/or process industries. It's a must-have reference.

Felt by many to be the Gold standard in orthopedic fracture care. The text is comprehensive, providing in-depth literature reviews and the authors prefered method of treatment. The text formatting style makes it difficult to quickly/easily obtain the "need to know" information regarding a particular topic. Overall, well worth it.

I read this book in my twenties and the story has stayed with me all my life. I have even been asked to read one of his poems on television from my hundred and ten year old copy of his life and works.

James Barke being the prime exponent in his knowledge of Robert Burns, has produced books of such detail about the bards early life that the reader is drawn back into the past to the Ayrshire countryside where Burns is living. Although he is a womaniser and a sometimes drunkard, he has such charm and charisma that almost everyone with whom he comes into contact cannot help but like him.

He is constantly in debt but it never seems to get him down. He scribles his hopes thoughts on anything available. He describes his contemporaries in such visible terms that you can see the poverty or the luxury in which they live.

James Barke conveys all of this in enviable detail and makes a mockery of other attempts to recontruct the life af Robert Burns. This book and the others in the series are 'must reads' for all admirers of Burns works

Perry's has been gathering dust on my bookshelf at home for years. I always think of it as the book to go to if you want to NOT find the answer to something. In my 20 year career and in my PE test effort, the only thing I ever used it for was to look up properties of substances. It is NOT friendly to the working engineer, since it quickly veers into arcane academic territory on every subject, or else is too general to be useful. This is a serious review of this book by a ChE PE, but I know this review will get panned by all, not because it is not useful, but because you do not agree with it.

This is the best book to show how distant are the theory and the practice of a Chemical Engineer.

Perry's Handbook has been found indispensable by chemical engineers, and a wide variety of other engineers and scientists, through six previous editions spanning more than sixty years. The NST/Engineers, Inc. reviewer, a Ph.D., PE favors the hardbound book as a desk reference, whereas he favors the CD format (ISBN# 0071344128) where a laptop or copying text or calculations are required. Users familiar with previous editions of Perry's will find additional text sections, tables, and figures. The reviewer did not detect deletions of any required material.

You will notice the increased use of SI units. Section 1, of thirty Handbook sections, "Conversion Factors and Mathematical Symbols", provides a rescue line for those of us much more accustomed to U.S., British, and older Metric units and who are not fully conversant with S.I. units. The first one-third of the Handbook lays the theoretical groundwork for a fuller understanding of its final two-thirds.

Section 2 provides physical properties data, including tables of constants for properties' correlations covering wide temperature ranges. Methods for the prediction and correlation of physical properties are explained. Section 3 summarizes mathematics through differential equations and statistics. Sections 4 through 7 may be considered short texts on "Thermodynamics", "Heat and Mass Transfer", "Fluid and Particle Dynamics", and "Reaction Kinetics".

In its eighty-four double column text pages, Section 8 covers the "Fundamentals of Process Dynamics and Control". It includes model predictive control, process optimization, unit operations control, process measurements, and concludes with controllers, final control elements, and regulators. Section 9, "Process Economics", takes the reader through calculations involved in investment and profitability decisions, cost control, and cost estimation. Starting with Section 10, "Transport and Storage of Fluids", and for most of the following twenty sections, the chemical engineering unit operations, details of more specialized theories and operating practices, calculation methods, interface studies between chemical engineering and other disciplines (i.e., Biochemical Engineering and Waste Management), and data specific to the topic being presented are given.

As previously stated, these latter sections, about two-thirds of the book, build upon an understanding of the fundamentals presented earlier. For example, Section 10; Section 11, "Heat Transfer Equipment"; Section 12, "Psychrometry, Evaporative Cooling, and Solids Drying"; Section 13, "Distillation"; Section 14, "Gas Absorption"; Section 15, "Liquid-Liquid Extraction"; Section 16, "Adsorption and Ion Exchange"; Section 17, "Gas-Solid Operations and Equipment"; and Section 18, "Liquid-Solid Operations and Equipment"; build on an understanding of Section 4, "Thermodynamics", Section 5, "Heat and Mass Transfer", and Section 6 "Fluid and Particle Dynamics". However, the book sections are all prepared to be rather self-sufficient so that readers without the earlier fundamental background can still gather useful working information.

The final twelve sections complete the review of unit operations and add important interdisciplinary studies. The sections are: "Solid-Solid Operations and Equipment"; "Size Reduction and Size Enlargement"; "Handling of Bulk Solids and Packaging of Solids and Liquids"; "Alternative Separation Processes"; "Chemical Reactors" (building on Section 7 "Reaction Kinetics"); "Biochemical Engineering"; "Waste Management"; "Process Safety"; "Energy resources, Conversion, and Utilization"; "Materials of Construction"; "Process Machinery Drives"; and "Analysis of Plant Performance";

Actually, a reasonable understanding of the contents of Perry's, including how to find and use the voluminous data, is equivalent to the text-based learning at the completion of a Master's degree in chemical engineering.

Well how is that, according to the data provided the fourth edition appeared in 1920!
