Your ship departed Venezuela for New York, loaded with 10,000 barrels of crude oil, whose average cargo temperature was 30°C (86°F). API is 25°. The volume correction factor (VCF) is .00045. If this cargo is heated to 100°F prior to discharge, how many barrels will you offload?

Correct Answer: Option B — 10,063
Calculate the volume change using the formula: New Volume = Original Volume * (1 + (VCF * Delta T)). Here, 10,000 * (1 + (0.00045 * (100 - 86))) = 10,000 * (1 + 0.0063) = 10,063 barrels. This adjustment accounts for the thermal expansion of the crude oil as it is heated prior to discharge.
