A cargo of fuel oil is loaded whose temperature is 66°F. API gravity is 36°. The volume correction factor (VCF) is .0005. A cargo temperature of 80°F is expected at the discharge port. If 9,000 barrels were loaded, how many barrels would you expect to unload?

A 8,910

B 8,937

C 9,063

D 9,090

AI Explanation

The correct answer is C) 9,063 barrels. The volume correction factor (VCF) is used to adjust the volume of a liquid based on changes in temperature. In this case, the cargo is fuel oil with an API gravity of 36°, and the temperature increases from 66°F to 80°F during transit. Using the VCF of 0.0005, the volume of the cargo would increase by 0.0005 x (80°F - 66°F) = 0.007, or 0.7%. With an initial volume of 9,000 barrels, the final volume at the discharge port would be 9,000 x 1.007 = 9,063 barrels. The other options are incorrect because they do not accurately account for the change in volume due to the temperature increase.
