Paperback. Condition: New. Print on Demand. This book delves into a critical but often overlooked factor in the precise measurement of fluid flow through orifice meters: the roughness of the pipe immediately upstream of the orifice plate. It examines the impact of pipe surface finish on the accuracy of flow measurements, a topic that has been of concern to engineers and scientists for decades. The author meticulously reviews previous research, highlighting the inconsistencies in reporting and measurement techniques that have hampered a comprehensive understanding of the roughness effect. The book presents the results of a rigorous experimental program conducted by the National Institute of Standards and Technology (NIST) to systematically investigate the influence of upstream pipe roughness on the orifice discharge coefficient. Using water, air, and nitrogen gas as test fluids across a range of orifice sizes and beta ratios, the author demonstrates the significant impact of pipe roughness on flow measurement accuracy, particularly for large beta ratios and high Reynolds numbers. The author's findings challenge existing standards for pipe roughness in orifice flow measurement, ultimately urging for a reassessment of these standards to ensure greater precision in flow measurement across various industrial applications. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
