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
