Problems and Countermeasures of the Safety Engineering Design Development

Liquids and gases are referred to as fluids. Fluid mechanics is a branch of mechanics, which studies the fluid stationary and moving mechanical laws and its application in engineering technology. Fluid is very extensively applied in the project. Such as: heating ventilation and gas engineering, water supply and drainage engineering, construction, civil engineering, municipal engineering, urban flood control engineering. They all take fluid as the working medium, and effectively organize it through various physical effects of the fluid. Therefore, it is particularly important to well learn hydrodynamics.
