Book Description
Measurements were made of air blast parameters at the midpoint of a line joining 2 equal weight explosive charges. The explosive used was 50/50 Pentolite with dual 1 or 8 lb spheres being detonated simultaneously. The pressure transducer employed was a BRL pancake pressure gage employing a synthetic piezoelectric ceramic as the sensing element. A SATISFACTORY SIMULATION OF REFLECTION OF A BLAST WAVE FROM A RIGID WAL WAS OBTAINED. The pressure-time histories of the colliding waves were measured using gages which were developed for side-on blast experiments. These measurements agree with data obtained by other techniques. The data constitutes the first direct measurements with calibrated gages, of the pressure-time history of a face-on blast at scaled distances as small as Z = 1.5 ft/lb (1/3). (Author).

Book Description
This book, written for the benefit of engineering students and practicing engineers alike, is the culmination of the author's four decades of experience related to the subject of electrical measurements, comprising nearly 30 years of experimental research and more than 15 years of teaching at several engineering institutions. The unique feature of this book, apart from covering the syllabi of various universities, is the style of presentation of all important aspects and features of electrical measurements, with neatly and clearly drawn figures, diagrams and colour and b/w photos that illustrate details of instruments among other things, making the text easy to follow and comprehend. Enhancing the chapters are interspersed explanatory comments and, where necessary, footnotes to help better understanding of the chapter contents. Also, each chapter begins with a "recall" to link the subject matter with the related science or phenomenon and fundamental background. The first few chapters of the book comprise "Units, Dimensions and Standards"; "Electricity, Magnetism and Electromagnetism" and "Network Analysis". These topics form the basics of electrical measurements and provide a better understanding of the main topics discussed in later chapters. The last two chapters represent valuable assets of the book, and relate to (a) "Magnetic Measurements", describing many unique features not easily available elsewhere, a good study of which is essential for the design and development of most electric equipment – from motors to transformers and alternators, and (b) "Measurement of Non-electrical Quantities", dealing extensively with the measuring techniques of a number of variables that constitute an important requirement of engineering measurement practices. The book is supplemented by ten appendices covering various aspects dealing with the art and science of electrical measurement and of relevance to some of the topics in main chapters. Other useful features of the book include an elaborate chapter-by-chapter list of symbols, worked examples, exercises and quiz questions at the end of each chapter, and extensive authors' and subject index. This book will be of interest to all students taking courses in electrical measurements as a part of a B.Tech. in electrical engineering. Professionals in the field of electrical engineering will also find the book of use.
