WHAT DOES BACK PRESSURE MEAN IN ENGLISH?

Back pressure

Back pressure refers to pressure opposed to the desired flow of a fluid in a confined place such as a pipe. It is often caused by obstructions or tight bends in the confinement vessel along which it is moving, such as piping or air vents. Because it is really resistance, the term back pressure is misleading as the pressure remains and causes flow in the same direction, but the flow is reduced due to resistance. For example, an automotive exhaust muffler with a particularly high number of twists, bends, turns and right angles could be described as having particularly high back pressure.

Definition of back pressure in the English dictionary

The first definition of back pressure in the dictionary is the pressure that opposes the motion of a piston on its exhaust stroke in an internal-combustion engine. Other definition of back pressure is the exhaust pressure in external combustion engines. Back pressure is also the local pressure that builds up when fluid flow is obstructed in the cardiovascular or urinary systems.
