Properties of Fluid Description of properties Formula Dimensional Formula Units
Specific Volume The volume is occupied by unit mass of fluid is known as specific volume. v=V/M M‾¹L³  m³/kg

Specific Gravity

 Specific gravity is defined as the ratio of weight (or) mass density of a fluid to weight.

It is denoted by by “S”

S=ρ gas / ρ air

S=ρ liquid / ρ water

Mass  Density

Mass density defined as the ratio of mass of fluid to it’s volume.

It is denoted by symbol rho “ρ”

 ρ = V/M  M‾³ kg/ m³

Weight Density

 It is defined as the ratio of weight of fluid to its volume.It is denoted by the “W”  W=ρ x g   ML‾² T‾²  N/m³
