Fluid Mechanics

Fluid Mechanics is the branch of physics that studies the behavior of fluids, including liquids and gases, under the influence of forces. It examines how fluids flow, deform, and transmit energy. Fluid mechanics is fundamental to understanding natural phenomena such as ocean currents, atmospheric circulation, and blood flow, as well as engineered systems like pipelines, aircraft, and hydraulic machines. The field is divided into fluid statics, which studies fluids at rest, and fluid dynamics, which studies fluids in motion. Governing principles include conservation of mass, momentum, and energy. Fluid mechanics combines experimental observation, theoretical analysis, and numerical simulation. Its applications span engineering, geophysics, meteorology, and biology. Fluid mechanics provides the foundation for more specialized fields such as aerodynamics, hydrodynamics, and turbulence research.
