1 cubic foot of air at sea level weighs roughly 0.08 pounds (1.29 oz). Since buoyancy depends on the displaced fluid's weight, 1 cubic foot of air provides about 62.4 pounds of buoyancy in water. This means it can support an object weighing 62.4 pounds before sinking**.
FAQs & Answers
- How is the buoyancy of air calculated? Buoyancy of air is calculated based on the weight of the fluid displaced—in this case, water. One cubic foot of air displaces one cubic foot of water, which weighs about 62.4 pounds, thus providing that much buoyant force.
- What is the weight of 1 cubic foot of air at sea level? At sea level, 1 cubic foot of air weighs approximately 0.08 pounds or 1.29 ounces.
- Why does air provide buoyancy in water? Air provides buoyancy in water because it is less dense than water. When air displaces water, the upward buoyant force equals the weight of the displaced water, allowing it to support objects.
