Buoyancy and Fluid Pressure

Buoyancy and Fluids

• The upward force exerted by a fluid that opposes the weight of a partially or fully immersed object is known as buoyancy.

Pressure in Fluids

• The pressure at the bottom of a column of fluid is greater than the pressure at the top of the column.

Buoyant Force

• The magnitude of the buoyant force is proportional to the density of the fluid, the volume of the displaced fluid, and the gravitational acceleration.

Convection Currents

• The most common driving force of convection currents in fluid mixtures is differences in density.

Reference Frame for Buoyancy

• Buoyancy can occur in any reference frame, including a stationary or moving reference frame.
