Fluid mechanics is composed of two subfields: fluid statics, which is the study of fluids at rest; and fluid dynamics, which is the study of fluids in motion. This ability to predict the onset of turbulent flow is an important design tool for equipment such as piping systems or aircraft wings, but the Reynolds number is also used in scaling of fluid dynamics problems, and is used to determine dynamic similitude between two different cases of fluid flow, such as between a model aircraft, and its full. Fully Developed Flow Fully developed flow occurs when the viscous effects due to the shear stress between the fluid particles and pipe wall create a fully developed velocity profile. Water waves, or more generally interface problems in fluids, represent another target area for the program.
