How much positive buoyancy does a dive bell displace when at 193 ft3 of sea water?

To determine how much positive buoyancy a dive bell displaces when it occupies a volume of 193 cubic feet of seawater, we can use the principle of buoyancy which states that the weight of the fluid displaced by an object is equal to the buoyant force acting on that object.

Seawater has an approximate density of 64 pounds per cubic foot. Therefore, to find the weight of seawater displaced by the dive bell, we multiply the volume of the dive bell by the density of seawater:

193 ft³ (volume) × 64 lbs/ft³ (density) = 12352 lbs of seawater displaced.

This represents a positive buoyancy of 12352 pounds.

When looking at the provided answer choices, we find that B, which states 1952 lbs, does not appear to directly reflect the calculation, suggesting there may have been a misinterpretation or calculation error regarding the expected weight or its representation.

However, understanding the principle allows us to grasp the essence of why buoyancy matters in diving – the greater the positive buoyancy created by the volume of the dive bell displacing seawater, the safer and more stable it will be under these conditions. The correct understanding of buoyancy is crucial
