This book is intended for people who wish to know how pump systems work and specifically how centrifugal pumps are sized in detail and mostly intended for college or engineering students and professionals. The basic equations for calculating pump total head, N.P.S.H., pressure head anywhere in the system and others are derived from basic principles. This is a good overall review of the subject and a good reference manual. If you have forgotten how to size a pump this manual will tell you just about everything you need to know.
