n: a value used to quickly determine gas volume flow: it is derived from several factor, such as the basic orifice factor (Fb),and the pressure base factor (Fph)

n: see base pressure.

n: a factor used in the formula recommended prior to August 1992 for the calculation of gas volume flow. The factor adjusted the volume to a standard atmospheric pressure regardless of the location.

n pI: the number of Btus contained in a cubic foot of natural gas fully saturated with water at a specified pressure base and 60�F (15.5�C).

n: the pressure base that state regulations require for the reporting of gas volumes. The pressure base for reporting to the states of Texas, Oklahoma, and Kansas is 14.65 pounds. Louisiana and California pressure bases are 15.025 pounds and 14.73 pounds, respectively.
