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 |
