Buoyancy of one cubic foot of air
WebWell, air has a lower average density than water and cruise ship's have air submerged beneath the water (ie, between the ship's lower decks) which lowers the ship's average density to be less than that of water. So if you … WebSo if the density of the fluid in which the volume of air is immersed changes with depth, then the buoyant force will change with depth as well. Ok, so less force at a greater density or a greater depth. No, the opposite. The air will have the same density as the volume is provided as a constant (one cubit foot).

WebFirst we determine that a 3 cubic foot object in salt water would have 3x64 lbs of lift, or 192 lbs of buoyant force. If we subtract 192 from 400 we get 208 lbs. This means we need to generate 208 lbs of lift to make our object neutrally buoyant. We then divide 208 (the objects in water weight) by 64 (the weight of a cubic foot of sea water) to ...
