Related Terms

COMPRESSION STAGES

A term used to denote increase of pressure on a fluid by the use of mechanical energy in several steps or stages.

VALVE

A device which controls fluid flow direction, pressure, or flow rate.

COMPRESSOR VALVE

A valve in a compressor, usually automatic, which operates by pressure difference (less than 5 pounds per square inch or 35 kilopascals) on the two sides of a movable, single-loaded member and which has no mechanical linkage with the moving parts of the compressor mechanism.

STATIC HEAD

The pressure due to the weight of a fluid above the point of measurement.

FLUID MECHANICS

The science concerned with fluids, either at rest or in motion, and dealing with pressures, velocities, and accelerations in the fluid, including fluid deformation and compression or expansion.

ECCENTRIC VALVE

A rubber-lined slurry or fluid valve with an eccentric rotary cut-off body to reduce corrosion and wear on mechanical moving valve parts.

ANEROID FLOWMETER

A mechanism to measure fluid flow rate by pressure of the fluid against a bellows counterbalanced by a calibrated spring.

COMPRESSIBILITY

Measure of ability of being compressed. The change in volume of a unit volume of a fluid when subjected to a unit change of pressure.

COMPRESSION RATIO

The ratio of the absolute pressure at the discharge from a compressor divided by the absolute pressure at the suction. For internal combustion engines compression ration is absolute pressure at the end of compression stroke divided by absolute pressure at beginning of this stroke

VOLUME FLOW RATE

The volume of fluid flowing through the cross- section of a conduit in unit time at the pressure and temperature prevailing in that section.
