2b. A SUBMARINE War Vessel which can be considered as a closed pontoon, has 4 vertical equaliy sized diaphragms/ballast tanks (size of each is $1.6\mathrm{m}\times 1.4\mathrm{m}$ ) in series as shown in the figure. The submarine vessel (originally of elliptical section) can be approximated to be of a circumscribing rectangular section of $3.0\mathrm{m}\times 3.4\mathrm{m}$, and is built throughout with 1 inch thick metal alloy weighing $95,850\mathrm{N}/{\mathrm{m}}^3$. Determine the melacentric height of the SUBMARINE Vessel as soon as it surfaces above the sea water surface. Relative density of sea water is 1.03 . Assume the vessel with only the compartment weights separating the diaphragms, with proportionate weights for the front and rear portions of the vessel.
