Book excerpt: The Measurement of Air Flow: 5th Edition (in SI Units) deals primarily with the measurement (expressed in SI units) of the speed of air in motion relative to solid boundaries or surfaces. The methods described apply not only to air flow but also to the flow of other gases with little, if any, modification, except as regards the numerical values of the various physical properties occurring in the equations. Furthermore, much of the theory applies to the flow of both liquids and gases. Comprised of 13 chapters, this volume begins with an overview of the general principles of the pressure-tube anemometer used in measuring pressure difference from which the speed of flow can be deduced. The reader is then introduced to the characteristics of pitot and static tubes in incompressible flow; pitot and static observations in compressible flow; and the flow of air in pipes of circular cross-section. Subsequent chapters focus on the measurement of incompressible flow in pipes by pitot and static traverse methods; methods of flow measurement based upon the rates of cooling of hot bodies; and the measurement of pulsating flow. This book is intended for students and engineers and for other practitioners concerned with the measurement of the speed of air flow.

Available in PDF, EPUB and Kindle. Book excerpt: This project improved the accuracy of air flow measurements used in commissioning California heating and air conditioning systems in Title 24 (Building and Appliance Efficiency Standards), thereby improving system performance and efficiency of California residences. The research team at Lawrence Berkeley National Laboratory addressed the issue that typical tools used by contractors in the field to test air flows may not be accurate enough to measure return flows used in Title 24 applications. The team developed guidance on performance of current diagnostics as well as a draft test method for use in future evaluations. The series of tests performed measured air flow using a range of techniques and devices. The measured air flows were compared to reference air flow measurements using inline air flow meters built into the test apparatus. The experimental results showed that some devices had reasonable results (typical errors of 5 percent or less) but others had much bigger errors (up to 25 percent).

Book excerpt: This project improved the accuracy of air flow measurements used in commissioning California heating and air conditioning systems in Title 24 (Building and Appliance Efficiency Standards), thereby improving system performance and efficiency of California residences. The research team at Lawrence Berkeley National Laboratory addressed the issue that typical tools used by contractors in the field to test air flows may not be accurate enough to measure return flows used in Title 24 applications. The team developed guidance on performance of current diagnostics as well as a draft test method for use in future evaluations. The study team prepared a draft test method through ASTM International to determine the uncertainty of air flow measurements at residential heating ventilation and air conditioning returns and other terminals. This test method, when finalized, can be used by the Energy Commission and other entities to specify required accuracy of measurement devices used to show compliance with standards.

Available in PDF, EPUB and Kindle. Book excerpt: A practical guide to cutting-edge techniques for flow measurement and control Unlike any other book on the subject, this volume employs practical applications to illustrate flow measurement techniques in industrial processes. Drawing on their work at the Oak Ridge National Laboratory, five leading researchers present applications that test the limits of commercial flow instrumentation-in harsh environments, wide rangeability, and a host of challenging situations encountered in research and industry. This approach gives the reader highly effective tools for use in tackling a broad range of difficult flow measurement problems. It offers tremendous insight into what flow measurement is all about, from the underlying principles of the methodologies to state-of-the-art instrumentation-including such innovations as "smart" flow sensors. Introducing terminology, properties, units, and flow meters classification, the book: * Details signal conditioning and analysis techniques that will produce meaningful results * Offers tips on selecting the appropriate method for a given application * Shows how modeling can improve mass flow metering accuracy * Covers flow calibration and standards, as well as issues related to cost, maintenance, and ease-of-use of instruments * Addresses the effect of measurement uncertainty on calibration and field measurements. Clear, concise, and generously illustrated, Flow Measurement Methods and Applications is an invaluable resource for researchers and graduate students in physics, mechanical engineering, chemical engineering, and instrument engineering. It is a must-have reference for anyone wishing to assess flow processes accurately and reliably in the real world.

Available in PDF, EPUB and Kindle. Book excerpt: Techniques and Topics in Flow Measurement covers the applications and techniques of flow measurement. This definitive book provides guidelines for choosing appropriate techniques and assuring valid measurements as well as describes methods for treatment of calibration data in fluid flow under various conditions. The book also covers three systems of units: the SI system, the English Absolute Dimensional system, and the English Engineering system. Commonly used - and often misused - variables such as force, weight, and pressure are defined, and the relationships between the systems for these common variables are summarized. One of the many unique features of Techniques and Topics in Flow Measurement is the number of ready-to-use tables included throughout the text. Tables are provided for such commonly encountered variables as the saturation vapor pressure of water; the composition of dry air; the compressibility factor for air; air-free and air-saturated water density; viscosity of dry air, nitrogen, and other gases; and specific heat/specific volume ratios for dry air, water vapor, and moist air. Another unique feature of this book is the number of highly relevant examples. The author includes examples/exercises that demonstrate applications for density calculations; water vapor mixing ratio determination; gas viscosity interpolation; NIST guideline applications; buoyancy corrections; and more.
