Fluid mechanics is a physics-related science that involves applying laws of force and motion to fluids (gases and liquids), and fluid’s subsequent reaction. Fluid mechanics comprises two subcategories: fluid statics (hydrostatics), which is the study of fluids in a rest phase; and fluid dynamics, which is study of fluids that are moving. Fluid mechanics has significant use in aeronautical and hydraulic engineering, among other disciplines. Velocity, density, pressure and temperature as related to space and time are part of fluid mechanics. Density, compressibility and dynamic viscosity are properties that are often associated with fluids. Fluids motion is complex and often features nonlinear phenomena, such as turbulence, making it hard to explain precisely. Simple geometries, however, do allow for certain fluid mechanics methods to generate exact answers.
