GENERAL TERMS AND CONDITIONS (Continued)
3.4 Specific Gravity: The specific gravity of the gas shall be determined
by a recording specific gravity instrument as specified in Subsection
2.14 hereof. The arithmetical average of the hourly specific gravity
recording each day shall be deemed to be the specific gravity of the
gas for that day, during periods of flow only.
3.5 Supercompressibility: Measured gas volumes shall be corrected for
supercompressibility (deviation of the gas from the laws of ideal
gases) at the pressures and temperatures at which the gas is measured.
Except as otherwise agreed by Seller and Buyers, the factors for such
corrections shall be obtained from data contained in the A.G.A. Manual
for the Determination of Supercompressibility Factors for Natural Gas
developed under P.A.R. Research Project NX-19 completed in December
1962, or any subsequent revision or replacement thereof.
3.6 Atmospheric Pressure: The absolute atmospheric (barometric) pressure
at each measuring station shall be the pressure corresponding to the
elevation at such station, and shall be stated in pounds per square
inch. No atmospheric changes for weather shall be taken into account.
3.7 Gross Heating Value: The gross heating value of the gas shall be de-
termined by use of a recording calorimeter as specified in Subsection
2.13 hereof. The arithmetical average of the hourly gross heating
values so recorded each day, during periods of flow only, shall be
deemed to be the gross heating value of the gas for such day.
3.8 Measurement Responsibility: Subject to the provisions of Subsections
2.6 and 2.7 hereof, measurement of gas volumes and gross heating values
shall for all purposes of this FERC Gas Tariff, Original Volume No. 1
be as recorded on or computed from the measuring equipment and devices
installed and operated, or caused to be installed and operated, by
