Question 1247 Deck General

70% 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 gallons would you expect to unload?

A 375,354
B 380,646
C 491,535
D 498,465
AI Explanation

The correct answer is B) 380,646 gallons. To arrive at this answer, we need to calculate the volume of the cargo at the discharge temperature of 80°F, given the initial volume of 9,000 barrels at 66°F and the volume correction factor (VCF) of 0.0005. The formula to calculate the volume at the discharge temperature is: Volume at discharge temperature = Initial volume x (1 + VCF x (Discharge temperature - Initial temperature)) Plugging in the values: Volume at 80°F = 9,000 barrels x (1 + 0.0005 x (80°F - 66°F)) Volume at 80°F = 9,000 barrels x (1 + 0.0005 x 14°F) Volume at 80°F = 9,000 barrels x 1.007 Volume at 80°F = 9,063 barrels To convert this to gallons, we multiply by 42 (the number of gallons in a barrel), which results in 380,646 gallons. The other answer choices are incorrect because they do not accurately reflect the volume calculation using the given information and formula.
