Abstract:

The coefficient of expansion has been determined on two series of fuel oils using the Weptphal balance. The first series tested was the NRL group consisting of eight cracked residuums, seven blends of unknown base, and two shale oils. The second series is known as the A series and is made up of cracked residuums and fuels blended from suck reduums. The average coefficient of expansion for the A series is 0.000369 per degree F and the NRL series is 0.000361 per degree F. The results of the study of the A series show that the average variation of gravity determinations is 0.23 A.P.I as determined by eleven cooperative laboratories. The results in this report show that the present studies when considering the variations that may obtained by different observers.
