Book excerpt: Excerpt from The Theory of the Steam Turbine: A Treatise on the Principles The general scheme of the first edition has been retained; and although some of the principal problems have been elaborated a little more, an endeavour has been made to keep the general mathematical treatment within fairly simple limits. Some revision has been necessary in places owing to the rapid development of the turbine, new data, and, in a comparatively new subject, the inevitable modification of views. A word seems advisable in regard to the treatment of the problem of the reaction turbine. Several highly involved theories and arithmetical solutions of the problem have been published during the interval (notably by Engineering, 1906, Schmit and Koob), which have certainly assisted me materially in prosecuting the subject. A careful study of these solutions and their assumptions suggests, however, that fundamental simplifications are warranted. Mechanical restrictions are unavoidable and formidable, and it is difficult to avoid very arbitrary assumptions. A few experiments made to indicate the nature of some of the restrictions are given. It may further be noted, that the fact that two precisely similar sections of blading of different sizes have yet to be made is a primary difficulty. These difficulties lead to the conclusion, that extremely involved calculations which end in an inevitable compromise are unremunerative. Some of the notes in my first edition relating to labyrinthal leakage are not correct. A separate section has been added, the approximate theory and new experimental data being, I think, fairly concordant. The specific heat of superheated steam having been subjected during the last three or four years to very elaborate investigation, has, it is hoped, nearly reached finality. Nevertheless, some divergence yet existing between the results of the latest experimenters, I have not altered the values of the thermo-dynamic efficiencies of the original examples given in various tables and curves. The error involved by the substitution of current values of the specific heat is, however, not more than two or three per cent., and in no way affects the general conclusions. The temperature entropy diagram (B) has been revised to date, and all new examples based thereon. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
