A cargo of oil has a coefficient of expansion of .0005 per degree F. If this cargo is loaded at 70°F, and a cargo temperature of 90°F is expected at the discharge port, how many barrels would you expect to unload if you loaded 10,000 barrels?

Correct Answer: Option D — 10,100

The temperature rise of 20°F (90°F - 70°F) causes thermal expansion. The volume increase is calculated as: 10,000 barrels × 20°F × 0.0005 (coefficient of expansion) = 100 barrels. Adding this expansion to the loaded volume yields an expected discharge of 10,100 barrels.
