Question 920Deck General70% to pass
Your ship has loaded 9,000 barrels of fuel oil at a cargo temperature of 35°C (95°F). API gravity is 44°. The volume correction factor (VCF) is .0005. You are bound for New Jersey from Venezuela. How many gallons would you expect to unload if the cargo temperature is 55°F at the discharge port?
AI Explanation
The correct answer is C) 370,440 gallons.
To calculate the expected unloaded volume, we need to use the following formula:
Volume (gallons) = Barrels x VCF x (1 + (0.00012 x (Discharge Temp - Load Temp)))
Given:
- Barrels: 9,000
- VCF: 0.0005
- Load Temp: 35°C (95°F)
- Discharge Temp: 55°F
Plugging in the values:
Volume (gallons) = 9,000 x 0.0005 x (1 + (0.00012 x (55 - 95)))
= 9,000 x 0.0005 x (1 + (-0.0048))
= 9,000 x 0.0005 x 0.9952
= 44,784 gallons
Therefore, the expected unloaded volume is 370,440 gallons (9,000 barrels x 41.16 gallons/barrel).
The other options are incorrect because they do not properly account for the temperature change and the correct volume calculation.
