Question 1197 Deck General

70% to pass

Your ship has loaded 20,000 barrels of crude oil, departing Valdez, Alaska for San Francisco. When loaded the cargo temperature was 96°F. API was 15°. The volume correction factor (VCF) is .0004. If the cargo temperature is expected to be 56°F at the discharge port, how many gallons will be offloaded?

A 1,082,400
B 853,440
C 1,117,600
D 826,560
AI Explanation

The correct answer is D) 826,560 gallons. The key to solving this problem is to use the Volume Correction Factor (VCF) to adjust the original volume of 20,000 barrels based on the change in cargo temperature from 96°F to 56°F. The VCF of 0.0004 indicates that for every 1°F change in temperature, the volume changes by 0.0004 or 0.04%. To calculate the adjusted volume, we take the original 20,000 barrels and multiply it by the VCF for the 40°F temperature drop (40 x 0.0004 = 0.016). This results in a volume reduction of 16%, or 3,200 barrels. Subtracting this from the original 20,000 barrels gives us the adjusted volume of 16,800 barrels. Converting this to gallons (16,800 x 42 = 826,560) yields the correct answer of 826,560 gallons. The other answer choices are incorrect because they do not properly account for the temperature-based volume adjustment using the provided VCF.
