by calibration, test or mathematical calculation, or (c) by estimating the

quantity delivered by reference to actual deliveries during preceding periods

under similar conditions when the equipment in question was registering

accurately.

 

(2) Unit of Volume and Basis of Measurement. The unit of volume for all

purposes of this agreement shall be 1,000 cubic feet of gas. A "cubic foot of

gas" shall be the amount necessary to fill a cubic foot of space when the gas

is at a temperature of sixty (60) degrees Fahrenheit and an absolute pressure

of 15.025 pounds per square inch. The atmospheric pressure at the point of

delivery or redelivery shall be assumed to be 14.7 pounds per square inch

absolute.

 

Volumes shall be computed in accordance with the instructions contained

in Report No. 3, using the specific gravity method prescribed by paragraph

(72) for the determination of supercompressibility. In the event the

viscosity specific gravity or temperature of the gas are not within the

variations provided in paragraph (62) of Report No. 3, the applicable factor

F, shall be calculated by such method as may be mutually agreed upon.

 

Volumes shall be corrected for temperature and specific gravity as

provided below.

 

The flowing temperature of the gas shall be determined by means of a

recording thermometer of standard manufacture and the arithmetic average of

the chart record during the periods of time during which gas was flowing

shall be the temperature at which such gas was delivered for the period of

such chart record. Volumes shall be corrected for each degree of variation in

the average temperature from sixty (60) degrees Fahrenheit.

 

The specific gravity of the gas shall be determined by a recording

gravitometer of standard manufacture except that if neither party considers

it necessary to install a recording gravitometer, spot tests shall be made

with an Edwards type gas balance, or by such other method as shall be

mutually agreed upon. If a recording gravitometer is used, the arithmetic

average of the chart record during the periods of time during which gas was

flowing shall be the specific gravity of the gas for the period of such chart

record. If the spot test method is used, the specific gravity shall be

determined
