Question 1247Deck 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 gallons would you expect to unload?
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.
