The boundary layer around a human hand, schlieren photograph. The boundary layer is the bright-green border, most visible on the back of the hand (click for high-res image). In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a bounding surface formed by the fluid flowing along the surface.

The process works by allowing normally unobservable changes in a fluid's refractive index to be seen, [1] and is accomplished by viewing the deflections that occur when light is refracted by a moving fluid. Because changes to flow rate directly impact the refractive index of a fluid, one can therefore photograph a fluid's flow rate (as well as ...
The layout of the Fatimid city of Al-Mansuriya in Ifriqiya founded in 946 was circular, perhaps in imitation of Baghdad. The choice of layout may have been a deliberate challenge to the Abbasid Caliphate. [23] The Fatimid architecture of Ifriqiya and Egypt followed Abbasid styles, as shown by the Great Mosque of Mahdiya and the Azhar Mosque in ...
Hydraulics (from Ancient Greek ὕδωρ (húdōr) ' water ' and αὐλός (aulós) ' pipe ') [2] is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases.
Pipe network analysis. In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
