Excerpt from A Treatise on Hydraulics In the present treatise the author returns to a subject which occupied his attention at intervals during a long period, and which always seemed attractive. Not only has Hydraulics formed part of his teaching, but he was much engaged in the early sixties in designing water turbines and centrifugal pumps, and has had on many occasions since to consider questions of flow, storage, and measurement of water. In 1876, he wrote the article "Hydraulics" for the ninth edition of the Encyclopoedia Britannica, which he has reason to think has been useful to many engineers. Strictly rational hydrodynamics, so far as it has been developed, is concerned mainly with fluids deprived of viscosity, and leads to results flagrantly at variance with the action of actual fluids. Hence in dealing with the practical problems of hydraulics the engineer has recourse to comparatively simple mechanical principles and simplified assumptions which furnish rough formulæ, which can be modified by empirical constants so as to be true to the necessary approximation over any required range of conditions. There now exists an enormous mass of experimental data relating to hydraulic problems, which has been accumulated during a period extending over two centuries, and which is of very varying trust-worthiness and importance.
