Hydraulics course is a compulsory course for independent undergraduate course, a self-taught examination for higher education in Jiangsu Province. It is a professional basic course for cultivating and testing the basic physical properties of liquids, the basic concepts and theories of hydrostatics and hydrodynamics, and their practical application skills in engineering. Hydraulics is a basic technical course for architectural engineering majors. Its task is to study the balance of liquid (mainly water), the law of mechanical movement and its practical application. The basic laws of hydraulic research are: first, the law of liquid equilibrium, that is, the relationship between various forces acting on the liquid when the liquid is in a static or relatively balanced state; The second is about the law of liquid movement, that is, the relationship between the force acting on the liquid and the moving elements, and the relationship between the moving characteristics of the liquid and the energy conversion. Because we need to use the equilibrium theorem, momentum theorem and kinetic energy theorem of mechanics department when learning the law of liquid equilibrium and the law of mechanical motion, the knowledge of physics, theoretical mechanics and advanced mathematics is the necessary basis for learning hydraulics.
