内容简介
Thiook is concerned with the Fluid Mechanics and Hydraulic experiments that future engineers should master. For the mechanical engineering related majors， it is crucial that the Fluid Mechanics fundamentals and its applications in the field of Hydraulic in various forms should be thoroughly understood. Fluid Mechanics is defined as the science that deals with the behavior of fluid at rest (fluid statics) or in motion (fluid dynamics) ， and the interaction of fluids with solids or other fluids at the boundaries. Fluid Mechanics is also referred to as fluid dynamicy considering fluids at rest as a special case of motion with zero velocity. Also， fluid mechanics itself is divided into several categories. The study of the motion of fluids that can be approximated as incomprele (such as liquids， especially water， and gases at low speeds) is usually referred to as hydrodynamics. A category of hydrodynamics is hydraulics， which deals with liquid flows in pipes and open channels. Of course it also has categories of Gas dynamics and aerodynamics. According to the latest requirements of mechanical major， great efforts are given in the Fluid Mechanics and Hydraulic parts in thiook. Consequently， the contents in thiook will be contributed by two parts： Fluid Mechanics (Lab 1 to Lab 3) and hydraulic (Lab 4 to Lab 14). The fundamental theories will be presented， ways of operation methods in order to shed light on theories will be shown， and illuminating lab reports will be developed. The experiment equipment of Fluid Mechanics iased on Armfield which is made in English， and the hydraulic experiments are equipped by Bosch Rexroth from Germany. Every experiment requires at least 2 hours and they are independent. It can be selected according to diverse requirements. It not only encourages the undergraduate student to enhance the operation ability， but also can be extended to treat advanced topics in graduate-level courses and to deal with realistic problems in an industrial context.
