A tank is loaded with 9,000 barrels of gasoline. The temperature of the product is 90°F (32°C), and it has a coefficient of expansion of .0008. What is the net amount of cargo loaded?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 8784 bbls
Standard oil measurement requires correcting volume to standard base temperature (60°F). With a temperature of 90°F, the cargo is 30°F above base. Multiplying 9,000 barrels by 30°F and the 0.0008 expansion coefficient gives 216 barrels expansion. Subtracting this from observed volume yields 8,784 net barrels.
