Furthermore, because the lower energy fluid in the boundary layer branches through the channels the higher energy fluid in the pipe centre remains in the pipe as shown in Fig. 4. Fig. 4. Velocity profile along a manifold. Thus, mass, momentum and energy conservations must be employed together for description of flow in manifolds.
Types of manifolds in engineering include: Exhaust manifold An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. Hydraulic manifold A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps Inlet manifold (or "intake ...
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.
Let M be a compact smooth manifold, f: M → M a diffeomorphism, and Df: TM → TM the differential of f.An f-invariant subset Λ of M is said to be hyperbolic, or to have a hyperbolic structure, if the restriction to Λ of the tangent bundle of M admits a splitting into a Whitney sum of two Df-invariant subbundles, called the stable bundle and the unstable bundle and denoted E s and E u.
A cylinder manifold is system of pipes and valves for using a group of gas cylinders, or boil-off from vacuum insulated evaporators, to feed a single supply line.The advantages of the manifold system as compared with using a single cylinder are increased capacity and reliability, and also the possibility of a centralized supply for multiple users.

In the theory of smooth manifolds, a congruence is the set of integral curves defined by a nonvanishing vector field defined on the manifold. Congruences are an important concept in general relativity , and are also important in parts of Riemannian geometry .
