Air Compressors and Blowing Engines e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The following work deals with the construction of Blowing Engines and Air Compressors, and is reprinted from a series of articles which originally appeared in The Practical Engineer. The first chapter discusses the properties of air, and shows how to calculate the work required for compression under various circumstances. The second describes several experiments with compressors, and explains the methods of calculating the various efficiencies. The third deals with the theory of valves for equalisation of pressure, and the fourth is devoted to the construction of Blowing Engines. Chapter V. Com menees the description of Air Compressors. These have self-acting valves, and the remainder of the book is devoted to those with mechanically controlled valves.
