On a vessel of 34,000 tons displacement, a tank 80 ft. long, 60 ft. wide and 30 ft. deep is half filled with fresh water (SG 1.000

AI Explanation
The correct answer is D) 40,100. The free surface constant for a tank is calculated using the formula: Free Surface Constant = L x B^3 / 12, where L is the length of the tank, B is the width of the tank, and the tank is assumed to be half-filled with liquid. In this case, the tank dimensions are 80 ft long, 60 ft wide, and 30 ft deep, and the tank is half-filled with fresh water (specific gravity 1.000). Plugging these values into the formula, we get: Free Surface Constant = 80 ft x (60 ft)^3 / 12 = 40,100 The other options are incorrect because they do not match the result of the formula for the given tank dimensions and liquid characteristics.
