The liquid mud tanks on your vessel measure 30'L by 15'B by 6'D. The vessel's displacement is 968 T and the specific gravity of the mud is 1.8. What is the reduction in GM due to a pair of these tanks (p/s) being slack?
AI Explanation
The correct answer is D) .87 foot.
The reduction in GM (metacentric height) due to a pair of slack liquid mud tanks (port and starboard) can be calculated using the formula:
Reduction in GM = (2 x L x B x D x (SG - 1)) / (Displacement)
Where:
L = Length of each tank (30 feet)
B = Breadth of each tank (15 feet)
D = Depth of each tank (6 feet)
SG = Specific gravity of the mud (1.8)
Displacement = 968 tons
Plugging in the values:
Reduction in GM = (2 x 30 x 15 x 6 x (1.8 - 1)) / 968
= (2 x 30 x 15 x 6 x 0.8) / 968
= .87 foot
The other options are incorrect because they do not match the calculated value of .87 foot.
