Question 2436Deck Safety70% to pass
On a vessel of 6500 tons displacement, a tank 30 ft. long, 32 ft. wide and 15 ft. deep is half filled with oil cargo (S.G. 0.948
AI Explanation
The correct answer is D) 3240.
The free surface constant for a tank is calculated using the formula: Free Surface Constant = (L x W^3) / 12, where L is the length of the tank, W is the width of the tank, and the tank is assumed to be half-filled.
In this case, the tank dimensions are 30 ft long, 32 ft wide, and 15 ft deep. Since the tank is half-filled, the effective depth is 7.5 ft. Plugging these values into the formula, we get:
Free Surface Constant = (30 ft x 32^3 ft^3) / 12 = 3240
The other options are incorrect because they do not match the correct calculation. Option A) is not a valid answer, and options B) 1336 and C) 2731 are incorrect numerical values that do not match the proper calculation.
