Abstract
THE need for a second edition of this admirable manual within a relatively short time amply justifies the encomiums which were paid to the first edition on its publication in 1940. It was, in fact, an appropriate and even a necessary adjunct to the same author‘s "Text Book of Applied Hydraulics", and clearly it has been found helpful by a number of engineers and students engaged on problems connected with liquid flow. The opportunity has been taken to amplify the original text by adding some new paragraphs to improve the balance of the work, and at the same time to bring it up to date. These additions have been introduced in such a way as not to disturb the arrangement of the original material, which remains unaltered. Hydraulics is largely an empirical science, and the application of reliable standards of measurement is necessary to its satisfactory development. New methods, some of them indirect, as in the case of the Allen salt-velocity principle, are continually being evolved, and, among other recent improvements, the author notes the adoption of standardized forms of pipe inlet in the Annis suction pipe meter now being used in that type of differential head meter. The manual will be found enhanced in usefulness by its revision and extension.
