Question 2597Deck General70% to pass
Your vessel is carrying 84,000 barrels of oil for discharge. The cargo hoses have an inside diameter of 14 inches. When four hoses are connected to the manifold, the container around the manifold must hold a total of how many barrels?
AI Explanation
The correct answer is B) Four barrels.
The reasoning is as follows:
1) The cargo hoses have an inside diameter of 14 inches. This means the cross-sectional area of each hose is approximately 153 square inches (pi * 7^2).
2) With four hoses connected to the manifold, the total cross-sectional area is 612 square inches.
3) Assuming a standard barrel height of 42 inches, the volume of the container around the manifold must be able to hold four barrels to accommodate the total cross-sectional area of the hoses.
The other answer choices are incorrect because:
A) Three barrels would not provide enough volume.
C) Twelve barrels would be excessive.
D) Sixteen barrels would also be excessive.
