Upstream and downstream valves refer to the positioning of valves in relation to the flow of fluid in a piping system. Upstream valves are located before a specific point in the system, controlling the flow entering that point, while downstream valves are positioned after that point, regulating the flow exiting it. These designations help in maintenance, troubleshooting, and ensuring proper fluid control within the system.
they could sail upstream and down stream
both. upstream is under the hood, and the downstream is by the catalytic converter.
one upstream and one down stream on in the manifold up stream the one in or behind the converter down stream
2 one in exhaust stream and one after converter! one upstream and one down stream ,doen stream oxygen sensor is in exhaust pipe after the converter. upstream sensor is ahead of converter.
Coordination between upstream relays for a overcurrent fualt on down stream.
a lock is a system that allows ships to travel upstream and down stream
The up stream is closest to engine and down stream is farest from engine
It has both an up and a down stream oxygen sensor.
Contour lines crossing a small stream will point upstream as they represent the elevation change of the terrain. This means that the elevation increases as you move in the upstream direction.
Three altogether. Two upstream and one down stream.
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
There is one upstream and one downstream.
