NPCA Buoyancy White Paper Section 1- Buoyancy Guide
NPCA Buoyancy White Paper Section 1- Buoyancy Guide Intro Buoyancy is defined as the tendency of a fluid to exert a supporting upward force on a body placed in a fluid ( , a liquid or a gas). The fluid can be a liquid, as in the case of a boat floating on a lake, or the fluid can be a gas, as in a helium-filled balloon floating in the atmosphere. An elementary application of Buoyancy can be seen when trying to push an empty water bottle downwards in a sink full of water. When applying a downward force to the water bottle from your hand, the water bottle will stay suspended in place. But, as soon as you remove your hand from the water bottle, the water bottle will float to the surface.
212 B.C.), established the theory of floatation and defined the buoyancy principle. Apparently (while in his bath) Archimedes realized that submerged objects always displace fluid upward (water in the bath rose while he was submerged).
