BRITISH THERMAL UNIT

(Btu) 1. A unit of heat energy equal to the heat needed to raise the temperature of 1 pound of air-free water from 60 to 61 F at a constant pressure of 1 standard atmosphere; it is found experimentally to be equal to 1054.5 joules. Also known as sixty degrees Fahrenheit British thermal unit (Btu60/61). 2. A unit of heat energy that is equal to 1/180 of the heat needed to raise 1 pound of air-free water from 32 F (0 C) to 212 F (100 C) at a constant pressure of 1 standard atmosphere; it is found experimentally to be equal to 1055.79 joules. Also known as mean British thermal unit (Btumean). 3. A unit of heat energy whose magnitude is such that 1 British thermal unit per pound equals 2326 joules per kilogram; it is equal to exactly 1055.05585262 joules. Also known as international table British thermal unit (BtuIT).

MOLAR VOLUME

The volume occupied by one molecular mass in grams (g mole) under specific conditions. For an ideal gas at standard temperature and pressure it is 0.0224 m3/g mole.

Abbreviated cmHg.

MILLIMETER OF MERCURY

A unit of pressure, equal to the pressure exerted by a column of mercury 1 millimeter high with a density of 13.5951 grams per cubic centimeter under the standard acceleration of gravity; equal to 133.322387415 pascals; it differs from the torr at the bottom used for hauling bulk materials. mineral engineering See mining engineering.

GAS-OIL-RATIO (GOR)

The gas volume flow rate, relative to the oil volume flow rate, both converted to volumes at standard pressure and temperature.

DRAPER EFFECT

The increase in volume at constant pressure at the start of the reaction of hydrogen and chlorine to form hydrogen chloride; the volume increase is caused by an increase in temperature of the reactants, due to heat released in the reaction.

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.
