Question 1246Deck General70% to pass

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?

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.
