Your ship has loaded 6,000 barrels of gasoline, at a cargo temperature of 50°F, departing New Jersey bound for Florida. API gravity is 55°. The volume correction factor (VCF) is .0006. How many barrels would you expect to unload if the cargo temperature is 90°F at the discharge port?

Correct Answer: Option D — 6,144

Temperature increases from $50^\circ\text{F}$ to $90^\circ\text{F}$ ($40^\circ\text{F}$ rise). Expansion is $6,000 \times 0.0006 \times 40 = 144$ barrels. Adding expansion to initial volume gives $6,144$ barrels expected at the discharge port, complying with standard marine petroleum custody transfer calculations.
