Excerpt from Handbook of Hydraulics: For the Solution of Hydraulic Problems
In applied hydraulics rational theory must give place to experimental knowledge. Though every particle of flowing water moves in accordance with definite fixed laws, such laws are intricate and imperfectly understood. In many instances the basic formulas used in hydraulic computations are derived from theoretical considerations, but they must invariably be corrected by experimental coefficients and frequently they become thereby so transformed as to bear but a slight resemblance to the original formulas.
Many thousands of experiments on flowing water have been performed during the last two centuries, the results of which form the basis of our present science of hydraulics. These experiments present many incongruities and as they do not cover the range of conditions required in practice, it is difficult to devise from them accurate working rules and formulas. The hydraulic engineer is therefore confronted with the task of making what appears to be the most reasonable application of the available data to each problem that he encounters.
A great number of empirical formulas have been devised, which provide an indirect method of transferring experimental results to practical problems. In using such formulas, however, the engineer should not lose sight of the fact that results obtained by them will be subject to errors corresponding to the discrepancies in the experiments on which the formulas are based.
The active interest in experimental research during recent years has been productive of such a rapidly increasing number of hydraulic formulas that engineers generally are not in a position to make critical comparisons and select those that possess the greatest merit. The result has been a tendency to cling to the old and accepted formulas.

Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of applied hydraulics, a field that has been revolutionized by centuries of meticulous experimentation. The author recognizes that while theoretical principles form the foundation, practical applications often require adjustments and corrections based on empirical data. This underscores the importance of experimental knowledge, as theoretical formulas often need to be refined through real-world observations. The text explores the complexities of water flow, analyzing a wide range of phenomena like the behavior of water through orifices, the dynamics of weirs, and the intricate calculations involved in pipe flow. It presents a comprehensive overview of established formulas and methods while also advocating for newer, more accurate, and streamlined approaches. The author's work provides a valuable resource for engineers and students, offering a pragmatic approach to solving hydraulic problems, emphasizing the need for both theoretical understanding and practical application. The book's insights on the relationship between theory and experiment remain essential for navigating the challenges of applied hydraulics.
