Book Description
Excerpt from Pumping by Compressed Air In preparing this book, I have endeavored to place in the hands of the student a comprehensive theoretical study of the subject, and at the same time instruct the Operating engineer in the practical economy essentials of the actual installation. To realize the first, I have quoted from the works of Professors Elmo G. Harris, George Jacob Davis and Carl R. Weidner, and to realize the last, I have incorporated an article by Mr. Arthur H. Diamant together with my own data Obtained as before stated. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Compressed Air: Theory and Computations After five years trying-out of the first edition the second has been prepared with the view to eliminate all errors and ambiguities and to add matter of value where possible without burdening the text with illustrations and descriptions of matter of only temporary value, such as machines and devices that are in use today but may be succeeded by better ones in a few years. It is the author's opinion that current practice, in the general form of machines and their details, can best be studied in trade circulars, of which there are many very creditable productions illustrating and describing a greater variety of machines than can possibly be shown in a text-book. A new chapter has been added on centrifugal fans and turbine compressors. The author has found a need for a clear, concise presentation of the theory underlying such machines, and believes that a more general knowledge of the technicalities of the subject will lead to material betterment of the cheaper forms of fans that make up the greater portion of the total in use. Appendix B, on design of Logarithmic charts, should be welcome to most students since such matter has not appeared in textbooks in common use. Compressed air has long held the Held for rock drilling underground, though electricity has several times attempted to get into that business. At one time it seemed that compressed air would prove the best motive power for underground pumps, but in more recent years the improvements in centrifugal pumps seem to give electricity the advantage. In general, it may be assumed that where rotation is desired electricity will have the advantage, while where rapid reciprocating motion is desired air will have the advantage. In the latter class are all kinds of pneumatic hammers, which have revolutionized several industries since they have been introduced. It is not the intention to enumerate here the applications of compressed air. It is a very versatile, willing and good-natured servant. It offers a fascinating field for the inventor and its usefulness and already numerous applications will surely increase.

Book Description
Excerpt from British Progress in Pumps and Pumping Engines Where little power is required, hot air engines are quite in place for powers up to about I horse-power, they are very economical and require but moderate attention. Such motors would often prove the best in country man sions, in farms and under Similar conditions. Compressed air is a valuable source of motor power. It can be carried in pipes for considerable distances with out appreciable loss of pressure, always provided that the air compressor is of the right design and construction; otherwise the loss of power and the cost of compression are apt to be very heavy. Electric motors are coming more and more to the front for pumping purposes, but an essential condition for the use of such power is this, that current is available at a reasonable cost. The advantages under suitable condi tions of electricity are obvious. It is always ready no time is lost in starting there is no condensation of steam. No doubt users of electric power have their own troubles. If the diameter of the cable be too small, or if there are too few strands, there will be a very sensible loss of power, while with too large a cable the first cost will be excessive. But if a cable of suitable diameter be selected, the waste of power will be trifling. Where an electric motor is used three-throw single-acting pumps are the best, as these give a more even distribution of power, which is essential in electric driving.

Excerpt from Compressed Air: Its Production, Uses, and Applications To limit the consideration of the properties of air when sim ply compressed above the ordinary pressure of the atmosphere was believed to be wanting in scope to make the treatment of the subject complete; this work includes, therefore, a consider ation of the properties of air below atmospheric pressure, for the reason that we are surrounded by an atmosphere compressed by gravity, but it is used in the arts in many ways much below atmospheric pressure, even approaching the zero condition of a vacuum, so that, remote as the connection appears, this subject of partial pressures below the atmosphere properly belongs to a treatise on compressed air.

Book Description
Excerpt from The Transmission of Power by Compressed Air The subject of Compressed Air and Compressed Air Machinery offers a wide field for useful investigation. It has been attempted in these pages to add something to the scanty stock of its literature. Compressed Air has become a most efficient and powerful agent in the hands of the modem engineer. Its applications are rapidly growing, both in extent and importance. The subject demands careful attention and study. There can be no doubt that the great waste of energy that to-day accompanies the use of Compressed Air is due, not only to sickly design and faulty construction of machines, but very largely also to the general ignorance of the principles of thermodynamics.
