Question 1240 Deck General
70% to passYour 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 barrels will be offloaded?
A
19,680
B
19,712
C
20,288
D
20,320
AI Explanation
The correct answer is A) 19,680 barrels. The reasoning is as follows: 1. The volume correction factor (VCF) is 0.0004, which means the volume of the cargo changes by 0.04% for every 1°F change in temperature. 2. The cargo temperature changes from 96°F to 56°F, a difference of 40°F. 3. The volume of the cargo will decrease by 0.04% x 40 = 1.6%. 4. 20,000 barrels x 0.984 (1 - 0.016) = 19,680 barrels. The other options are incorrect because they do not correctly apply the VCF to calculate the adjusted volume at the discharge temperature.
