5. Formula To Find: PSIA Pressure
14.7 + Gauge Pressure
6. Formula To Find: Compressor CFM Using The Time Method
Tank Gallons X .536 X PSIG Increase / Total Seconds
7. Formula To Find: Motor Max AMP Draw Before Damage Begins
Motor Data Plate AMPS X Data Plate Service Factor
FORMULA SYMBOLS & DEFINITIONS:
/ = divide
X = multiply
+ = add
AMPS = Abbreviation of the plural for Ampere, a unit of electrical current
CFM or cfm = Abbreviation of Cubic feet per minute - a unit of measurement of the flow of a air/gas or liquid that indicates how much volume in cubic feet pass by a stationary point in one minute.
OD = Abbreviation for Outside diameter is a dimension commonly used to specify the size of tubing or pipe.
PSIA or psia = Abbreviation for Pounds per square inch absolute (including atmospheric pressure)
PSIG or psig = Abbreviation for Pounds per Square Inch Gauge
RPM or rpm = Abbreviation for Revolutions per minute is a unit of frequency of rotation: the number of full rotations completed in one minute around a fixed axis. It is used as a measure of rotational speed of a mechanical component.
