Question 2441Deck Safety70% to pass
On a vessel of 7000 tons displacement, a tank 35 ft. long, 30 ft. wide and 4 ft. deep is half filled with fuel oil (S.G. 0.962
AI Explanation
The correct answer is D) 31,328.
To calculate the free surface constant for a partially filled tank, the formula is:
Free Surface Constant = (L x W^3) / 12
Where:
L = Length of the tank (in feet)
W = Width of the tank (in feet)
Given:
- Tank length = 35 ft
- Tank width = 30 ft
- Tank depth = 4 ft
- Tank is half-filled with fuel oil (S.G. 0.962)
Plugging the values into the formula:
Free Surface Constant = (35 ft x 30^3 ft^3) / 12
Free Surface Constant = (35 ft x 27,000 ft^3) / 12
Free Surface Constant = 31,328
The other answer choices are incorrect because they do not match the correct calculation using the provided tank dimensions and the formula for free surface constant.
