What is Fluid Dynamics?
Fluid dynamics refers to a subcategory of the science of fluid mechanics, with the other subcategory being fluid statics. While fluid statics deals with fluids that are at rest, fluid dynamics is concerned with fluids that are in motion. Any matter in a gas or liquid state can be considered a fluid. Fluid dynamics is a discipline with many relevant applications in our modern world, most notably because it contains the study of aerodynamics, and also because it comprises part of weather prediction. A typical fluid dynamics problem may include such variables as velocity, temperature, and density. All of the physical sciences, including fluid dynamics, are governed first and foremost by the laws of conservation. These state that the total amounts of energy, mass, and linear momentum in a closed system remain constant, and that energy and mass can neither be created nor destroyed. That they may change forms, it is true, but they cannot disappear or come from nothing. These laws constitute
