Back pressure (or backpressure) is the term for a resistance to the desired flow of fluid through pipes. Obstructions or tight bends create backpressure...

: 445  Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these...

plugs are usually subject to huge amount of back pressure that occurs in the pipeline, so the back pressure must be calculated accurately in order to prevent...

lowering the back-pressure even further creates a new imbalance between the exit and back pressures (exit pressure greater than back pressure), figure 1g...

children — the mouth-to-mouth method was preferable to the rocking method, back-pressure arm-lift, and other manual methods. Based on this recommendation, the...

above. More advanced exhaust brakes have exhaust pressure modulation (EPM) that controls the back pressure which in turn improves the braking performance...

water into the exhaust pipe cools the exhaust gas and thus lessens the back-pressure at the engine's cylinders. In marine service, the exhaust manifold is...

supersonic velocities. Simply: propellants pressurized by either pumps or high pressure ullage gas to anywhere between two and several hundred atmospheres are...

periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used. It is a diving mode...
