The temperature derating factor to be used in the design formula in Sec. 192.105 is determined as follows: ------------------------------------------------------------------------
Temperature
Gas temperature in degrees Fahrenheit (Celsius) derating factor
(T)------------------------------------------------------------------------250 F (121 C) or less................................ 1.000300 F (149 C)........................................ 0.967350 F (177 C)........................................ 0.933400 F (204 C)........................................ 0.900450 F (232 C)........................................ 0.867------------------------------------------------------------------------ For intermediate gas temperatures, the derating factor is determined by interpolation.
