A topological space that is "locally Euclidean" in the sense that every point is contained in an open set that is homeomorphic to an open set of Euclidean n-space . Additional conditions such as differentiability are often imposed. The manifold is the primary object of study in differential geomentry.
A topological manifold is a locally Euclidean Hausdorff space. (In Wikipedia, a manifold need not be paracompact or second-countable Ck manifold is a differentiable manifold whose chart overlap functions are times continuously differentiable. A âˆž or smooth manifold is a differentiable manifold whose chart overlap functions are infinitely continuously differentiable.
A manifold is an abstract mathematical space in which every point has a neighbourhood which resembles Euclidean space, but in which the global structure may be more complicated. In discussing manifolds, the idea of dimension is important. For example, lines are one-dimensional, and planes two-dimensional.
A tube, usually of cast metal, with one or more flanged or screw-threaded inlets and two or more flanged or screw-threaded outlets for pipe connections. To make a number of copies of anything by a single operation.
1. A device used to hold two or more gauges with fluid passages and flow provisions; used for testing ans servicing purposes. 2. A conduit-like device used to channel the air/fuel mixture into an engine. 3. A conduit-like device used to duct the exhaust gas out of an engine.
A type of distribution fitting in which a single source is directed to multiple outlets, or vice versa. Caution! Using a common distribution fitting in reverse to merge multiple streams may create dead volume. Special manifolds are available for this application.
The branch pipe arrangement that connects several input pipes into one chamber or one chamber into several output pipes. A filter manifold connects several input pipes from the filter septa back into one common pipe.
1. an accessory system of piping to a main piping system (or another conductor) that serves to divide a flow into several parts, to combine several flows into one, or to reroute a flow to any one of several possible destinations. 2. a pipe fitting with several side outlets to connect it with other pipes. 3. a fitting on an internal combustion engine made to receive exhaust gases from several cylinders.
A term used mainly with reference to blow moulding and sometimes with injection moulding equipment. It refers to the distribution or piping system which takes the single channel flow output of the extruder or injection cylinder and divides it to feed several blow moulding heads or injection nozzles.
In automotive engineering, an intake manifold or inlet manifold is a part of an engine that supplies the fuel/air mixture to the cylinders. An exhaust manifold or header collects the exhaust gases from multiple cylinders into one pipe.
In scuba diving manifold is used to connect two diving cylinders (tanks) with breathing gas, allowing longer dive times. This configuration provides several advantages when more than usual gas is needed. Diving with two or more cylinders is associated with technical diving. =Function= Longer and deeper dives require high amounts of breathing gas.
a subsea assembly that provides an interface between the production pipeline and flowline and the well. The manifold performs several functions, including collecting produced fluids from individual subsea wells, distributing the electrical and hydraulic systems and providing support for other subsea structures and equipment.
A device that performs the same function as a false bottom. It consists of copper tubing which is slotted on the bottom with a hacksaw. This device allows the removal/separation of the sweet liquor from the grain during sparging.
A junction at which various tubing loops meet. Made of brass, copper, or plastic with a header and several ports to interface with pex tubing. Designed to install in a closet wall, between the studs, with an access door.
A vessel supplied with boiler steam from which many auxiliaries are supplied. !-- google_ad_client = "pub-8826792545718317"; google_ad_width = 468; google_ad_height = 60; google_ad_format = "468x60_as"; google_ad_channel ="0630871714"; google_page_url = document.location; google_color_border = "666666"; google_color_bg = "FFFFF7"; google_color_link = "333333"; google_color_url = "006600"; google_color_text = "999999"; //-- Mansard Roof A railway coach or van roof, which in cross section has a flat central portion and sides which slope downwards.
