Question 933 Deck General

70% to pass

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?

A 9,900
B 9,990
C 10,010
D 10,100
AI Explanation

The correct answer is D) 10,100 barrels. The cargo's coefficient of expansion is 0.0005 per degree Fahrenheit. If the cargo is loaded at 70°F and the temperature increases to 90°F, the volume of the cargo will expand by 0.0005 x (90°F - 70°F) = 0.01 or 1%. Therefore, if 10,000 barrels were loaded, the expected unload amount at the discharge port would be 10,000 barrels + (10,000 barrels x 0.01) = 10,100 barrels. The other answer choices are incorrect because they do not accurately account for the 1% expansion in the cargo volume due to the temperature increase.
