What is Fluid Mechanics? Fluid Mechanics is a branch of physics that studies both static and dynamic fluids. Its ideas are also employed in astrophysics, biology, meteorology, geophysics, and civil, chemical, mechanical, and biochemical engineering. Fluid statics and fluid dynamics are the two major branches of fluid mechanics. Why is it Important? Why is fluid mechanics so important? Why do we need to learn about it? Fluids are essential in our daily lives, as we all know. For example, water is used for everything from drinking to generating electricity. Using engineering, we investigate the possibilities of fluids for a variety of new applications and functions. Understanding how fluids react under various stresses and atmospheric conditions are possible thanks to fluid physics. Large-scale projects like hydroelectric power plants and hydraulic machinery result from fluid mechanics research, but it all starts with a little lab experiment. As a result, the tools and equipment uti...
