Density and specific volume - thermodynamics, Mechanical Engineering

Assignment Help:

DENSITY (ρ ):

Density is defined as mass per unit volume; Density = mass/ volume; = m/v, kg/m³

P for Hg = 13.6 × 103 kg/m³

for water = 1000 kg/m³

Specific Volume (ν):

It is defined as volume occupied by the unit mass of the system. The unit of it is unit is m³/kg. Specific volume is reciprocal of density.

= v/m; m³/kg
