You may assume that tank internal pressure is always in equilibrium with the ocean's hydrostatic pressure and that the inlet pipe to the tank is at the bottom of the tank and penetrates the hull at the "depth" of the submarine. Consider a ballast tank, which can be modeled as a vertical half-cylinder $(R=8 \mathrm$ is important in maintaining the boat's attitude, determine the weight of water in the tank as a function of depth during the dive. The amount of water admitted is controlled by air pressure, because seawater will cease to flow into the tank when the internal pressure (at the hull penetration) is equal to the hydrostatic pressure at the depth of the submarine.

A submarine submerges by admitting seawater $(S=1.03)$ into its ballast tanks. An inverted open tank is held in place by a force R as shown in Fig P2.41.
