Excerpt from The Centrifugal Pump, Turbines, and Water Motors: Including the Theory and Practice of Hydraulics, (Specially Adapted for Engineers) In the third edition I added a. Method of Turbine design, mainly graphical, for which I was indebted to Professor Rateau, whose work Traite des turbo-machines, well deserves perusal, and is one of the leading works on the subject. In this, the fourth edition, additions have been made to Chapter XXVII., and I have added an extra chapter comprising descriptions of Centrifugal Pumps for high lifts, and of Fans capable of producing considerable pressures. There are several other minor additions, and the typographical errors which appeared in the third edition have been corrected.
