This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...area of an entropy diagram gives thermal units. For the method of drawing it see the paper already referred to, and M. Boulvin's book, vol. iii., p. 41. Captain Sankey determines each point from the intersection of the lines of equal pressure and equal volume. The term "entropy" d 0 was first adopted by Clausius to denote the integral. The method of drawing entropy diagrams is first claimed for M. Belpaire in 1872, and is described by Schottler (p. 109), who lays down clearly the difference between the diagrams of heat and of pressure, and by Professor Zeuner. In England the subject has been treated by Mr. Macfarlane Gray, who calls entropy the i p diagram. Professor Stodola says that by means of Combustion at constant jtrsssurt I 1--I I I I I I.-t 1 Horizontal Scale orf Entropy. Area British Thermal Units, Fig. 117.--Entropy Diagram. a properly constructed entropy diagram, all questions having reference to the cycle in gas engines can be solved easily and quickly by the graphic method, and with sufficient accuracy for practical purposes. To the engineer it affords the best way of handling the science of thermodynamics. German scientists have derived from it a new word, namely, "heat toning," which may be described as the excess of energy set free See Proceedings of the Institution of Mechanical Engineers, July, 1889. by chemical combination, the final products being cooled to the same temperature as the original. The tones of heat may best be determined by studying a cycle of combustion at constant volume. Note.--Although this chapter is headed "Theory of the Gas Engine," it practically applies equally to engines driven with oil vapour, spirit, alcohol, or any other forms of internal combustion motors.
