Question 1242 Deck General

70% to pass

A tank is loaded with 9,000 barrels of gasoline. The temperature of the product is 80°F (27°C), and it has a coefficient of expansion of .0008. The net amount of cargo loaded is _______________.

A 8,944 barrels
B 8,856 barrels
C 9,144 barrels
D 9,072 barrels
AI Explanation

The correct answer is B) 8,856 barrels. The key to this problem is understanding the concept of volumetric expansion due to temperature changes. The coefficient of expansion provided (0.0008) represents the fractional change in volume per degree of temperature change. To calculate the net amount of cargo loaded, we need to adjust the initial 9,000 barrels to account for the temperature increase from the reference temperature (likely 60°F). The formula to calculate the adjusted volume is: Adjusted Volume = Initial Volume x (1 + Coefficient of Expansion x Temperature Change). Using the given values, the calculation is: 9,000 barrels x (1 + 0.0008 x (80°F - 60°F)) = 8,856 barrels. The other options are incorrect because they do not properly account for the volumetric expansion due to the temperature increase.
