Your ship has loaded 8,000 barrels of gasoline at a cargo temperature of 36°C (97°F). API gravity is 54°. The volume correction factor (VCF) is .0006. You are bound for New Jersey from Ecuador. How many barrels would you expect to unload if the cargo temperature is 55°F at the discharge port?

Correct Answer: Option A — 7,798

Temperature decreases from $97^\circ\text{F}$ to $55^\circ\text{F}$, a $42^\circ\text{F}$ drop. Contraction equals $8,000 \times 0.0006 \times 42 = 201.6$ barrels. Rounding gives $7,798$ barrels expected at the discharge port, applying standard marine petroleum temperature correction factors.
