Principles of Turbomachinery - Second Edition

The 4 stars rating was based upon the following components of evaluation: 1. Contents: It contains theory about every type of machine that could be characterized "turbomachine" 2. Order: It's order of presenting the contents isn't perfect,but it is one of the best.A good characteristic of the order it follows,is the presantation of principle, at the same chapter, for every machine it concerns. I could say it is ordered not primarily by the machine type, but by the machine's principles. 3. Extras: It contains a very good and full chapter about cavitation.I think a more detailed aproach to this problem, can be found only in specialized books. 4. Drawings-Graphs: It's not off-course colourful but the graphs and drawings are clear and simple,providing good understanding. 5. Index: Index is a very ipmortant factor of useability of a book. Unfortunately this book does not provide a really good index,only one which contains just the basics.This is a minus of the book,because it significantly reduces the speed when looking for something. 6. Depth: The depth that aproaches things isn't the optimum. Some of the formulas represented should be escorted with a small derivation to give a better idea to the reader how to use them. This minus, fortunately takes rarely. 7. New ideas: It is a good thing that the book follows the changes of engineering on the subjects incluted.For example it gives more weight to Net Positive Suction Energy(NPSE) instead of the old idea N.P.S.Head. So,my final conclusion is "if you still dont have a general turbomachinery book,don't hesitate to buy this one".
