Book excerpt: Excerpt from Photometrical Measurements and Manual for the General of Photometry: With Especial Special to the Photometry of Arc and in Incandescent Lamps The topical form of discussion has been followed, and a certain amount of repetition has been considered advisable in order to permit concise treatment and definition of the subject matter. In this way, it was thought that the book would prove more useful for reference; and this has been further facilitated by the use of cross-references.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Light, Photometry and Illumination: A Thoroughly Revised Edition of "Electrical Illuminating Engineering" This book is designed as a text in illuminating engineering and a reference for the practicing engineer. It is the outgrowth of sets of notes written and compiled by the author for use in his classes at the Armour Institute of Technology, and of his previous book, "Electrical Illuminating Engineering." In the construction of this volume the author has freely consulted the volumes of the technical press and particularly the Transactions of the Illuminating Engineering Society, the Illuminating Engineer the Bulletin of the Bureau of Standards, and the Electrical World. It has been the aim of the writer to assemble the best ideas and thoughts available on the subject of artificial illumination and in so doing he has freely drawn from the works of eminent authorities on particular phases of this subject as will be seen from the references cited. In this connection grateful acknowledgment is made to the writings and investigations of Dr. H. E. Ives, Dr. A. S. McAllister, Dr. E. B. Rosa, Mr. M. D. Cooper, Mr. A. J. Sweet, Mr. A. A. Wohlauer and others whose excellent papers and kind permission to use them are greatly appreciated. The author also washes to express his appreciation of criticisms and suggestions by Dr. H. E. Ives, of the kindness of Mr. F. H. Bernhard in reading proof and criticising copy, and of the efforts of the publishers in editing the book.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrical Photometry and Illumination: A Treatise on Light and Its Distribution, Photometric Apparatus, and Illuminating Engineering This book is primarily intended as a text-book for second year engineering students. It contains in an amplified form the lectures delivered by the author during the session 1911. The subject of photometry and illuminating engineering has been somewhat neglected in the past, and whereas one finds scores of books on electrical machinery, there have been very few on photometry and lighting. Yet this subject is as important as, or even more so than, the design of dynamos and motors. It Is useless to raise the efficiency of generators and motors by 1 or 2 per cent. And afterwards to waste the power by improper illuminating engineering. Illuminating engineering is a combined science of physics and physiology. This has been far too little understood in the past, with the result that physiology has hardly been considered. Our knowledge of physiological science is still very meagre. We neither possess any apparatus with which we can measure the physiological quality of an illumination, nor have we been able to remove the difficulties which we encounter when lights of different colours are compared. For a long time - while englneers were busily engaged in perfecting the generating plant and the light-producing devices - the subject of illuminating engineering was left in the background, with the result that one often finds the finest buildings poorly lighted, not so much from the physical, as from the physiological standpoint. Especially, architects are to blame in this direction 3 any illumination is often considered good enough, as will be gathered from the fact that for a. Particular building costing the sum allocated by the architects for the lighting was only 100, in spite of the building being largely wanted for entertainments at night. Although the book is primarily intended for college students, it is hoped that it will be found useful by others interested in illuminating engineering, such as medical men, architects, teachers, and even the general public. The mathematics have been kept as elementary as possible, and persons not acquainted with higher mathematics may skip the deductions of the formulae without detriment.

Download or read book The Pentane Lamp as a Working Standard Classic Reprint written by E. C. Crittenden and published by Forgotten Books. This book was released on 2018-02-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Pentane Lamp as a Working Standard Since all flames depend upon combustion it is to be expected that their intensity will vary with the proportion of oxygen and Of other constituents in the air supplied to the gaseous fuel of the flame. T O maintain a flame in a constant condition requires, therefore, not only uniform fuel, but also a uniform proportion Of oxygen in the air supplied to the flame. Good ventilation is con sequently desirable for all work with flames, and is indispensable where lamps Of other kinds are to be compared with a flame standard. The quantity Of air which must be supplied depends largely on the size and number Of flames in the room and also on the method of ventilating. The flames themselves set up currents of air, and if possible these currents should be utilized to remove immediately from the room all the vitiated air coming from the lamps. A hood placed above the photometer with a rising pipe to lead the warm air out of the room is most effective. If the gases from the flames are allowed to diffuse into the room and are simply diluted by the air entering, a much larger amount Of fresh air will be needed. In such a case it has been estimated 5 that to keep the carbon dioxide content of the air down to 6 parts in 10 000, 3000 cubic feet of fresh air per hour must be supplied for each person in a room. A committee Of the American Gas Institute 6 has on this basis estimated that 36 900 cubic feet Of air per hour should be supplied for a photometer room where two persons work with a pentane lamp and a 5-foot gas flame, since in the production Of carbon dioxide the gas flame is approximately equivalent to six persons and the pentane lamp to four. In a room where air enters at the bottom and escapes at or near the top the quantity estimated as above (about I 2 000 cubic feet per hour for a pentane lamp) is probably ample for any purpose, and if care is taken to allow direct escape Of the flame gases a much smaller amount is sufficient.
