What is the rear pressure?
back pressure is usually a measure of fluid resistance and pipe pressure. A fluid, such as liquid or heavy gas, will move the pipe at the highest speed allowed by its condition. When the pipe conditions change, such as accessing or bending, the fluid in the pipeline slows down to match the new environment. When calculating, the data accumulation of the data in the network switch is backward.
The pressure -based pressure -based version is more common and very misleading. The real term concerns the resistance of the generated when the pipeline changes configuration, not a change in the momentary pressure behind it. The pressure change usually undergoes the name of the liquid hammer. When this energy hit the wall, it bounces like waves as they reach the edge of a cup. This has two main effects. First, it increases the pressure in the pipeline for a moment when the fluids first encounter a change. The second effect is to slow down the movement of all fluid in the pipeline, from change to source.
The first effect is commonly called a liquid hammer or a water hammer when they speak specifically about water. When the liquid encounters a change, it bounces back to the liquid that attempts to walk through the tube. This increases the liquid present in a small part of the pipeline to increase its pressure. This is a momentary change that ends as soon as the liquid begins to flow around the bend of the pipeline and does not happen again in this bend until the liquid flows continuously.
The second effect is to slow down the movement in the pipeline, the true meaning of pressure. The slowdown in a narrow or bent location prevents fluid from building so much momentum. This loss is translated back to the pipe, reducing the momentum of the entire current. This phenomenon is used to reduce the velocity of the substance when it leaves the pipe or to maintain fluid in the pipeline for a longer period of time.
In the world of computers, back pressure has a much different meaning. When a network switch or routing system fills its buffer data and can no longer take, sends the signals backto the source of broadcasting that it is full. The data created in the broadcast source is called pressure. This is an undesirable situation because the assembled data are easily damaged when they are finally sent.
