This early work first published in 1911 by Viktor Gelpke is both expensive and hard to find in its first edition. It details the mechanics of hydraulic turbines, their accessories, construction and notable turbine installations. This is a fascinating read for anyone interested in hydraulic engineering and its historical applications. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
