Centrifugal and axial flow Pumps

BOOK PRINCIPLESOF PHYSICAL SCIENCE,by Francis T. Bonner and Melba Phillips. 736 pages, illustrations, 6 X 9 in. Reading (Mass.), Addison-Wesley Publishing Co., Inc., 1957. Price, $7.50. As a new text for liberal arts students desiring a physical science course, this book should be of interest to general readers as well. The authors have assumed that this course would be the only one in college science, and so they have built their text around the central theme of the growth of man’s ideas concerning the physical world. There are thirty chapters devoted to various fields of science, including such topics as The Solar System, The Law of Universal Gravitation, Matter and Its Classification, Heat and the Conservation of Energy, Wave Motion, Rocks and Their Formation, etc. The sequence of chapters follows the historical development of the physical sciences, and so the whole picture is presented chronologically. The text is suitable for college freshmen and requires only a knowledge of elementary algebra. The text has been used successfully at Brooklyn College. CENTRIFUGAL AND AXIAL FLOW PUMPS, by A. J. Stepanoff. Second edition, 462 pages, diagrams, 6 X 9 in. New York, John Wiley 82 Sons, Inc., 1957. Price, $12.00. The second edition of this text has been expanded to include a chapter on “Water-Hammer Problems in Centrifugal Pump Systems,” new material on centrifugal-jet systems, thermal cavitation criterion, and complete characteristics of axial and mixed flow pumps. The original text has been revised to add design refinements and a new viscosity chart. Throughout, the author has included the developments in theory, design and application which have come about since the first edition was published in 1948. SYSTEMATIC ORGANIC CHEMISTRY, THEORY AND APPLICATIONS, by Hugh C. Muldoon and Martin I. Blake. 828 pages, diagrams, 6 X 9 in. New York, McGraw-Hill Book Co., Inc., 1957. Price, $7.75. Emphasizing biological applications, this text is intended for beginners in general or428

NOTES ganic chemistry. The book follows the general order of presentation used in Muldoon’s “Organic Chemistry,” but differs from it in purpose and content. The present text includes discussions of new theories and new interpretations, with much of the factual material set forth in tables to give more space for discussion of the newer theories. Although emphasis is on principles and applications, current industrial methods for manufacturing important synthetics are discussed. PHYSICS FOR SCIENCE AND ENGINEERING,by Robert L. Weber, Marsh W. White and Kenneth V. Manning. 618 pages, illustrations, 7 X 10 in. New York, McGrawHill Book Co., Inc., 1957. Price, $8.00. The present book has evolved from its predecessor “College Physics.” The objective is to introduce the basic concepts and principles of general physics for students of physics and engineering at the university level. Further, the book is designed to develop the reasoning power of the student instead of his memory. To achieve this goal, the authors have stressed the understanding of the fundamental ideas, principles and methodology of physics rather than mere fact and formula. TRANSISTOR CIRCUITS, by Rufus P. Turner. 160 pages, diagrams, 51 X 83 in. York, Gernsback Library, Inc., Price, $2.75 (paper).

New 1957.

The author, a licensed professional engineer, has prepared this practical work book for electronic technicians, engineers and experimenters. He lists over 150 practical transistor circuits, all of which he has tested himself. For those engaged in work using transistors, this handbook will save many hours of experimenting. Eleven chapters cover such devices as audio amplifiers, RF, IF and d-c. amplifiers, oscillators, power supplies, radio receivers, test instruments, etc. THERMODYNAMICS,by Virgil Moring Faires. Third edition, 543 pages, illustrations, 6 X 9 in. New York, The Macmillan Co., 1957. Price, $7.50. The third edition of this standard text has been issued because of the growth in the con-
