2.15 Mcf. The term "Mcf" shall mean 1,000 cubic feet of

gas.

 

2.16 British Thermal Unit or Btu. The term "British

thermal unit" or "Btu" shall mean the amount of heat required to

raise the temperature of one pound of distilled water 1 degree

Fahrenheit at 60 degrees Fahrenheit, at a constant pressure of

14.73 pounds per square inch absolute.

free of water vapor, and under a pressure equal to that of

30 inches of mercury at 32 degrees Fahrenheit and under a

standard gravitational force (acceleration of 980.665 cm

per second per second) with air of the same temperature and

pressure as the gas, when the products of combustion are
