In ASTM table no.54 for VCF which density is used.density in air or vacuum also if possible please write an article regarding ASTM tables.TIA.
ASTM Table 54 stands for evaluating VCF (Volume Correction Factor). On vertical side Tank Temperatures are given and horiontally Density @ 15 Deg C are given. Corresponding value for Tank Temperature and Density @ 15 Deg C is VCF.
Now it comes to one mind, as to how to calculate Density @ 15 Deg C. You have to draw a composite sample of crude or product and measure the sample for Temperature and Density and use ASTM Table 53, to evaluate Density @ 15 Deg C. In Table 53, Vertical side you have Sample Temperature and horiontally Sample Density and the corresponding value is Density @ 15 Deg C. Having calculated Density @15 Deg C and VCF, calculation of quantity is as under-
Gross Volume (A) -Unit in KL
Less : Water Volume (B) Unit in KL
Nett Volume @ NT (A-B) - C Unit in KL
Tank Temp Unit in Centigrade
Density @ 15 Deg -- D - Unit in Kg/L
VCF (using Table 54) E - Factor
Volume at 15 Deg C - C * E - F Unit in KL
WRF ( Density @ 15 Deg C- 0.0011 ) - G - Factor
Quantity in Air F * G Unit in Metric Tonnes
Quantity in Vac F* D Unit in Metric Tonnes
N.B : When softwares available to calculate VCF and calculations, I am afraid if anyone resort to basics.
