Excerpt from Pray's Steam Tables and Engine Constants: For Facilitating All Calculations Upon Indicator Diagrams, or Various Problems Connected With the Operation of the Steam Engine, From Reliable Data and With Precision
The density of steam is correctly given in this volume, taking Prof. Rankine as reliable, and no one today has the abstract facts on that property of saturated steam to any greater certainty than he had, and up to date no one has given facts to consider in place of his reasoning, nor with any approximate basis beyond their own conception of what might be. The tables here given will, to some extent, increase the amount of steam used in any place, but it is correct from present knowledge, and with Regnault's observations and results, and Rankine's verifications of those same results, we must be put in possession of far more accurate data, than the suppositions of theorists, before we attempt to alter the Rankine basis, for saturated steam, for the simple, but indisputable reason that his basis was entirely from Regnault's actual experiments, in using steam, under practically the same conditions that steam engines use it in practical work, while the density is assumed to a great degree in any case, the basis herein adopted is assumed only so far as the higher pressures are given, it is almost positively known for some of the lower range.

Verkäuferbewertung 4 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book gathers together key data for boiler testing, duty performance of pumping engines, and indicator diagram computations. Prior to its publication, computation of these values was mostly inaccurate and required a great deal of referencing from various sources. The author's goal was to compile all essential data into one easy-to-use volume, using the most accurate computations possible. Of particular note is the author's expansion of the Regnaults results for saturated steam. He also provides a full translation of Regnault's important papers. The author explains the importance of accurately computing clearance, provides methods for doing so, and incorporates the results into the computation of the ratio of expansion. The book also includes tables for finding the factors of evaporation and the economy of feed-water heating. This book remains one of the most important references for engineers, containing proven formulas, methods, and data for accurately assessing the performance of steam engines. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9780282917388_0
