One of the best hydraulic calculation guides. The nature of the phenomenon is described in detail and examples of calculation are given. Excellent for both universities and the design of hydraulic structures. The fourth edition of the Hydraulic Calculation Handbook, like all the previous ones, is a summary of the main formulas, definitions, experimental coefficients, auxiliary tables and graphs useful in the production of hydraulic calculations. The text is limited to brief explanations necessary to facilitate the use of the material collected in the handbook.
