Unformatted text preview: o F: TIME (minute) 5 10 15 20 25 30 Pressure (psi) 4.9 8.05 8.45 8.50 8.50 8.50 Sample : Gasoline Room Temperature: 70.3 o F Barometric Pressure : 760 mm Initial Room Temperature : 71.6 o F Uncorrected Vapour Pressure : 8.5 lb/sq.in Correction : - 1.4 lb/sq.in Reid Vapour Pressure : 7.2 lb/sq.in Sample Calculation : Reid vapour pressure = (8.5 +.1-1.4)=7.2 lb/sq.in Discussion : From table 1 we can see that the pressure increases as the time passes until it become steady , at that point the vapour pressure is found .Some corrections must be done due to temperature effect and bourdon gauge usage. Conclusion : In this experiment,we were able to calculate vapour pressure of gasoline by applying Reid method .P* was found to be ( 7.2 lb/sq.in )at 100 o F....
