FORMULA SYMBOLS & DEFINITIONS:/ = divide X = multiply+ = addAMPS = Abbreviation of the plural for Ampere, an unit of electrical current
CFM or cfm = Abbreviation of Cubic feet a minute - an unit of measurement from the flow of an air/gas or liquid that indicates how much volume in cubic feet pass with a stationary point in one minute.
OD = Abbreviation for Outside diameter is a dimension commonly used to specify the size tubing or tubing.
PSIA or psia = Abbreviation for Pounds per square in . absolute (including atmospheric pressure)
PSIG or psig = Abbreviation for Pounds per Sq . in . Gauge
RPM or rpm = Abbreviation for Revolutions per minute is an unit of frequency of rotation: the quantity of full rotations finished in one minute around a fixed axis. It is used as a measure of rotational speed in a mechanical component.
