Excerpt from A Text-Book on Hydraulics Including an Outline of the Theory of Turbines The treatment of turbines and water wheels has been re stricted to an outline of the theory, but several illustrations showing typical American practice have been included. For these the author is indebted to the courtesy of manufacturers, to whom credit is in every case given in the text. The aim has been to unify the theory, the treatment of all specific cases being based upon the same general principles and equations, and a general notation for velocities and their direction-angles being adopted which it is hoped will be found simple and helpful. This unification includes the theory of turbine pumps. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
