A
. What is the free surface constant for this tank
B
1152
C
1336
D
2390
AI Explanation
The correct answer is D) 2390. To calculate the free surface constant for a partially filled tank, the formula is: Free Surface Constant = (Length x Width^3) / 12. Given the tank dimensions of 30 ft. long, 32 ft. wide, and 18 ft. deep, with the tank half filled, the free surface constant can be calculated as (30 ft x 32 ft^3) / 12 = 2390. The other answer choices are incorrect because they do not match the result of the free surface constant calculation using the provided tank dimensions and cargo specifics.
