Chapter 6: Buoyancy and Specific Gravity

Fluids

commonly liquids and gases, are substances that flow, thus, having no

definite shape.

Fluid statics

study of non-moving fluids. density does not change regardless of the force or pressure it experiences.

Buoyant Force

an upward force experience by an object submerged in a liquid

Archimede’s Principle

the object experiences, whether it is partially or fully submerged, is equal to the weight of the fluid the object displaces.

Archimede’s Equation

Fb = pfVfg

Specific Gravity

is the ratio of a substance’s density to a standard, conventionally

water.
