abbr: volatile organic compound.

volatile organic carbon.

adj: readily vaporized.

n pi: those hydrocarbons that are readily vaporized.

n: a readily vaporized compound composed of carboncontaining molecules derived from living organisms.

n: the scientific study of volcanoes and volcanic phenomena. Also called vulcanology.

n: the unit of electric potential, voltage, or electromotive force in the metric system.

n: potential difference or electromotive force, measured in volts.

n: an instrument used to measure, in volts, the difference of potential in an electrical circuit.

n: The ratio of the volume of solid phase grains of drilling fluids to the total volume of drilling fluids in drilling .

n: 1. actual volume of fluid put out by a pump, divided by the volume displaced by a piston or pistons (or other device) in the pump. Volumetric efficiency is usually expressed as a percentage. For example, if the pump pistons displace 300 cubic inches (4,916 cubic centimetres),but the pump puts out only 291 cubic inches (4,769 cubic centimteres) per stroke, then the volumetric efficiency of the pump is 97%. 2. for compressors, the ratio of the volume of gas actually delivered, corrected to suction temperature and pressure, to the piston displacement.
