n: a machine that uses centrifugal force to separate substances of varying densities. A centrifuge is capable of spinning substances at high speeds to obtain high centrifugal forces. Also called the shake-out or grind-out machine.

n: An item of solids-removal equipment that removes fine and ultrafine solids. It consists of a conical drum that rotates at 2000 to 4000 rpm. Drilling fluid is fed into one end and the separated solids are moved up the bowl by a rotating scroll to exit at t

a device that separates materials by density through a centrifugal motion.

n: a type of engine governor that prevents hunting (an engines speeding up and slowing down as it seeks to run at the speed dictated by the engine governor.) A compensator on the governor anticipates the engines return to its set speed. When an engines speed goes faster than the set speed, the compensator drops the engines rpm;when engine speed drops below set speed, the compensator increases the engines rpm. Normally, engine operators set the compensator to keep the drop small. With a small speed drop, the governor and compensator quickly make the engine go back to control speed. See govemo1;hunting.

n: a cliff or relatively steep slope that separates level or gently sloping areas of land.

n: a surge of engine speed to a higher number of revolutions per minute (rpm),followed by a drop to normal speed without manual movement of the throttle. It is often caused by a faulty or improperly adjusted governor.

n: rate (commonly given in rpm) at which an action resulting from applied forces causes or tends to cause two adjacent parts of a body to slide relative to each other in a direction parallel to their plane of contact.

n: the speed, measured in revolutions per minute, at which the rotary table is operated.

n: The speed of rotary.

String RPM.

abbr: revolutions per minute. RQ abbr: reportable quantity. RSPA abbr: Research and Special Projects Administration (DOT).

relative permeability modifier.

revolutions per minute.

n: an extended cliff or steep slope, produced by erosion or faulting, that separates two level or gently sloping areas, i.e., an escarpment.
