(a) Lighter
Scenario: A tanker ship is transporting 5000 barrels of 38° API crude oil.
Task: Calculate the total weight of the crude oil in metric tons.
Hints:
1. **Calculate the volume in gallons:** 5000 barrels * 42 gallons/barrel = 210,000 gallons 2. **Determine the specific gravity:** 38° API translates to a specific gravity of approximately 0.83 (you can use an online API gravity calculator). 3. **Calculate the mass in pounds:** 210,000 gallons * 0.83 * 8.34 pounds/gallon ≈ 1,450,000 pounds 4. **Convert to metric tons:** 1,450,000 pounds / 2204.6 pounds/metric ton ≈ 657.9 metric tons
Therefore, the total weight of the crude oil in metric tons is approximately **657.9 metric tons**.
This chapter delves into the technical aspects of converting barrels of crude oil to metric tons. The process involves understanding the relationship between volume, density, and mass.
1.1 Density Calculation:
The conversion relies heavily on the oil's density, which is represented by its API gravity. This value indicates the oil's relative density compared to water. A higher API gravity signifies lighter oil.
The conversion between API gravity and specific gravity (density relative to water) is crucial. This conversion can be done using established formulas or readily available tables.
1.2 Volume Conversion:
The volume of the crude oil is usually expressed in barrels, a standard unit in the oil industry. Converting this volume from barrels to gallons is a straightforward multiplication by 42, as a barrel is equivalent to 42 US gallons.
1.3 Mass Calculation:
Utilizing the calculated density and volume, the mass of the crude oil can be determined. This involves multiplying the volume in gallons by the density (specific gravity) and the density of water (approximately 8.34 pounds/gallon).
1.4 Metric Ton Conversion:
The final step involves converting the mass, typically expressed in pounds, to metric tons. A metric ton equals 2204.6 pounds, allowing for a direct conversion by dividing the mass in pounds by this conversion factor.
Example:
For a specific example, we can follow these steps to convert 7.4 barrels of 36° API crude oil to metric tons:
Therefore, 7.4 barrels of 36° API crude oil is approximately equivalent to 0.992 metric tons.
