A number of rivers are known to have reversed the direction of their flow, either permanently or temporarily, in response to geological activity, weather events, climate change, tides, or direct human intervention.
Reverse flow may refer to: In engine technology a reverse flow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. Reverse logistics, i.e. goods/waste flowing in the distribution network having consumers as point of origin; Reverse electron flow is a mechanism in microbial metabolism
The reverse flow design is generally considered [according to whom?] to be inferior to a crossflow design in terms of ultimate engineering potential for two reasons. Firstly, there is limited space when inlet and exhaust ports are arranged in a line on one side of the head meaning a reduction in port area compared to a crossflow head.
Back siphonage is not to be confused with backflow; which is the reversed flow of water from the outlet end to the supply end caused by pressure occurring at the outlet end. [51] Also, building codes usually demand a check valve where the water supply enters a building to prevent backflow into the drinking water system.
Reverse psychology is often used on children due to their high tendency to respond with reactance, a desire to restore threatened freedom of action. Questions have, however been raised about such an approach when it is more than merely instrumental, in the sense that "reverse psychology implies a clever manipulation of the misbehaving child". [5]
Showing outlet flow velocity in a pipe. In outlet boundary conditions, the distribution of all flow variables needs to be specified, mainly flow velocity. This can be thought as a conjunction to inlet boundary condition. This type of boundary conditions is common and specified mostly where outlet velocity is known. [1]
Backflow is a term in plumbing for an unwanted flow of water in the reverse direction. [1] It can be a serious health risk for the contamination of potable water supplies with foul water. In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl.
A common source of unintentional backfeeding is an electrical generator (typically a portable generator) that is improperly connected to a building electrical system.A properly installed electrical generator incorporates the use of a transfer switch or generator interlock kit to ensure the incoming electrical service line is disconnected when the generator is providing power to the building.
