Centrifugal Pump Design 1st Edition

Best book I have seen for centrifugal pump design so far...

I'm very deceptionated with this book.I must recognize that the general structure of the book is quite good, but the problem is not that.The problem with the book begins with the formulas. It has to much errors. Seems that the autor hasn't had the time for a technical review. Some of the formulas has several tipographic mistakes, and appear different on the computer program listings.I have invested some time reviewing the results of the programs and a can't get the results that he shows. and in the listings of the program the formulas are written so differently that I don't understand why he introduced o where did he get the conversion factors.Let my list below some of the troubles I have found reviewing the listing of the program loss:1 Several varable names are incorrect (that is not much important)2 If you do a dimensional analysis of the leakage formula, the way it is written is wrong. You get incompatible units respect to flow.And this is only the begining. Seems to be tough and I need to do a more deep review in order to give a detailed list of errors in the book. I could be grateful if someone help me to do that.
