Question 2437 Deck Safety

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.
