Density
Physical property defined as the mass of a substance per unit volume
Density
Can indicate composition and state
Specific Gravity
compares the density of a substance to the density of a reference substance
Specific Gravity
Dimensionless quantity
Weight Density
Also known as specific weight
Weight Density
Weight of a substance per unit volume
Pressure
is the force exerted by a fluid at rest
Pressure
Varies with depth due to the weight of the fluid above
Pascal’s Principle
When pressure is applied to a confined fluid at rest, that pressure change is transmitted undiminished throughout the fluid in all directions
Archimedes’ Principle
An object submerged in a fluid experiences as upward buoyant force equal to the weight of the fluid it displaces
Absolute pressure
Total pressure measured relative to a perfect vacuum
Gauge Pressure
Pressure measured relative to atmospheric pressure, effectively excluding the atmospheric pressure from the measurement
